Sig P365 Review | Does It Live up to the Hype Among Gun Enthusiasts?

Since its introduction at SHOT Show 2018, the Sig Sauer P365 has been acknowledged as a formidable challenger in the arena of concealed-carry handguns, alongside popular alternatives like the Glock 43 and Smith & Wesson M&P Shield. The Sig Sauer P365 flaunts subcompact size for concealed carry and a polymer grip that can accommodate 10-round, 12-round, or 15-round mags. This Sig P365 review highlights everything you need to know about the gun. We also reviewed Glock 43 and Smith And Wesson M&P 2.0 for you.

Sig P365 Review - Does It Live up to the Hype?

If you’ve been following us for a while, you may already know that we’re pretty big Glock fans and that Sig Sauer handguns have never really been our cup of tea, apart from a couple of exceptions. The main reason why Sig products never struck us as impressive is that they didn’t offer the right combination of features required for today’s gunfighting. Most Sig guns are double-action/single-action (DA/SA) pistols, which we’re not fond of.

If you’re a newer shooter, you know exactly what we’re talking about. Even if the trigger is excellent in terms of weight, reset, travel, and so forth, if the shot isn’t consistent on each pull, you’ll always find yourself thrown off. If you’ve ever tried any of Sig’s earlier products, you know that their first trigger pull tends to be quite heavy and long, whereas the second pull is comparatively light and short. This trigger action simply isn’t for us.

It’s also worth pointing out that earlier Sig pistols were notably bulky and heavy, which is why they’re kind of swept under the rug nowadays. Don’t get us wrong, Sig pistols were pretty impressive when they were first released, but the problem is that as time went by, firearm technology continued to advance at a notably fast pace, and newer materials were used by many manufacturers. Sig seemed to have missed that seminar, though.

Having been overshadowed by almost all other firearm manufacturers, Sig finally got the memo and released a couple of polymer striker-fired handguns that have taken the market by storm. We’re, of course, talking about the P320 and P365. However, they did suffer a little bit with the Sig Sauer P320, but then boom, it was adopted by the U.S. Army as their primary handgun, granting the pistol a great deal of momentum. And while here, why not check the SIG P250 compact review.

Ever since the adoption of the Sig P320 by the army, nothing of noteworthy significance seemed to have been going for Sig Sauer, but then the company released the Sig P365 and the rest was history. The revelation of the Sig365 at SHOT Show 2018 may have had the biggest impact of all Sig-related news. Despite the sheer excitement associated with this news, the reception of the Sig Sauer P365 was shrouded by a bit of hesitation.

The hesitant reception is a result of then-recent news of drop-safety issues associated with the P320. Sig Sauer did solve these issues by carrying out a voluntary upgrade, but that didn’t seem to erase the stigma around Sig’s releases. Nevertheless, the P365 was put to the test and it was nothing short of impressive. Continue reading as we’re about to dissect the Sig Sauer P365 and disclose some valuable information.

Sig P365 Specifications



Semi-Automatic, Striker-Fired


10+1 or 12+1


9mm Luger







Barrel Length







Drift-Adjustable XRay3 Day/Night



As implied by the above-listed Sig P365 specs, it’s a purpose-made CCW. One of the most impressive things about this handgun is that it can accommodate a slide and frame that are slightly smaller than the G43’s as well as append four rounds to it. You’d expect such an exigent feat to come at the expense of comfort and functionality, but Sig Sauer did an admirable job balancing all of these aspects beautifully.

Why should you consider buying the Sig P365? To put it simply, this is an 11-round 9mm that becomes almost invisible when put onto your waistline or used as a pocket pistol. Other pistols don’t dare compete with the P365 when it comes to size and comfort.

Is it a faultless pistol, though? Not by a long shot, sadly. The P365 Sig does suffer from a few mishaps which we’re going to report on further down this Sig Sauer P365 review.

First Impressions

Our first impression of the Sig P365 is that it’s one of the smallest handguns we’ve ever got our hands on. It’s remarkably easy to carry around, which is why it’s considered by many aficionados as one of the best CCW pistols on the market, if not the best. Moreover, it’s extremely comfortable to shoot with. The pistol comes with a couple of 10-round mags: one has a pinky extension and the other is flush-fitting.

Like we already mentioned in the introduction, the Sig P365’s capacity can be extended, as the manufacturer has released 12-round and 15-round mags. However, keep in mind that the overall length of the pistol will be extended slightly if you go for a larger capacity. A P365 equipped with a 12-round mag flaunts almost twice the capacity of its three main competitors: the Glock 43, Walther PPS M2, and Smith & Wesson M&P Shield.

It’s worth noting that the P365 is advertised as a 10+1 pistol, which is righteous, but you must keep in mind that loading a full magazine while having one bullet in the chamber is a pain in the neck because it requires you to force the magazine into the grip. The P365 flaunts a high-visibility front sight, with a tritium vial highlighted by a green ring. The rear sight, on the other hand, features two vials and is well-serrated for glare reduction.

We’ll be dissecting each of these components in great detail further down the article, but all things considered, the Sig Sauer 365 seems to be quite a promising pistol right out of the box, especially when you take into consideration the ton of noise it made for itself in a market that’s saturated and crowded with top-notch concealed-carry firearms. We’ll be comparing the P365 with other similar competitors very shortly, so stick around. To give you a sneak peek, take a look at our Ruger LCP 2 Review.


From the moment we began testing the Sig Sauer P365 Nitron Micro-Compact, something was different about it, and not in a bad way at all. We’ve tested a few of Sig P365’s main competitors such as the Glock 43, and even though we were impressed with their performance and ergonomics, they didn’t quite feel the same way the Sig Sauer P365 9mm felt.

The grip is nothing short of superior; it’s extremely comfortable and firm, allowing for accurate shooting. Keep in mind that you can always get Sig Sauer P365 accessories that’ll make the grip even better for you.

The design of the 365 is greatly influenced by the P320 X-Series, especially in terms of the undercut of the trigger guard and the stippling. The pistol’s smooth undercut enables you to get a higher grip, which in turn allows for flatter shooting and better control. We’re quite fond of how well the pistol in the webbing of our hands, which is a result of the cut beavertail and backstrap of the grip. Certainly one of the nicest grips we’ve tried.

Upon closer inspection, we’ve noticed that the back of the slide was located fairly low in our hands. Not really sure where that is? It’s exactly where the cover plate of the striker is located when you’re holding the gun. Compared to other single-stack 9mms, the Sig P365’s bore axis is extremely low, which is strange to see because the vast majority of older Sig releases had notably a high bore axis compared to their competitors.

We couldn’t help but notice that a lot of people’s buying decisions are majorly influenced by the height of the bore axis, which we think is absolutely ridiculous. Yes, some pistols with a higher bore axis will tend to flip, but that doesn’t mean that you can’t shoot them with great efficiency. With regard to the stippling on the Sig P365’s grip, it’s extremely comfortable and helps the pistol sit firmly in the hand without being harsh on the skin.


When it was time to test the trigger, once again, we were astonished. As stated by the manufacturer, this is a 6lbs trigger. We didn’t utilize a trigger scale to measure, so we’re going to take the manufacturer’s word for it. What’s so strange about the P365’s trigger, however, is that it feels much lighter than its stated weight. It’s unbelievably crisp for a striker-fired pistol. We didn’t expect it to fire as seamlessly as it did, quite honestly.

What’s even more impressive is how short the trigger reset is. Initially, the trigger’s take-up is quite light and quick. However, once you reach the point where the resistance could be felt in the stroke, you’ll begin to notice the travel being around the quarter-inch mark. Even if you press through the stroke, you’ll notice a very smooth pressing action. We’re not sure how Sig Sauer managed to achieve that, but big kudos to them.

Note that once the trigger breaks, there won’t be any noteworthy over-travel. We like the fact that the trigged is designed to break with around 0.375-inch open space behind it, rather than breaking when it’s close to the guard opening’s rear. Another thing that sets the Sig Sauer P365 apart from competitors is the length of its pull. Whether your hands are on the smaller side or the larger side, you won’t have any problem with the trigger.


The Sig P365 is available in a range of variants that we’ll be highlighting shortly, but the original P365 comes equipped with Sig-Lite Night Sights, which are tritium-based night sights that are remarkably effective, especially when compared to some of the not-so-great sights equipped on other stock pistols from different manufacturers. And for your information, the P365 isn’t the only Sig Sauer pistol to come with these sights.

The earliest issues of the P365 were reported to have problems with their tritium vials. To be more specific, it was reported that they tend to break due to the striking recoil velocity of the slide. These earlier issues were sent back to the manufacturer, and from there, Sig Sauer decided to replace the Sig-Lite Night Sights with the then-recent XRay3 Day/Night Sights, which happen to be comparatively more superior.

We’re absolutely in love with the XRay3 Day/Night sights. Whether in broad daylight or in low-lighting conditions, these sights remain bright and effective. As we mentioned, the tritium vial on the front sight is adjoined by a green circle. The color is bright enough that it’s easy to pick up on it. With regard to the rear sight, on the other hand, it serves as a blacked-out sight when using the pistol in broad daylight, which is quite helpful.

In addition, the P365’s rear sight features two tritium dots that become quite apparent in low-lighting conditions. When shooting the pistol in broad daylight, the rear sight’s tritium dots are perceivable, but not quite noticeable that they become your first resort. If you’re a quick-shooter, you’ll find the front sight to be more effective than the rear sight due to its brightness. All things considered, we don’t have much to complain about here.

Recoil and Shootability

As far as the recoil and shoot ability of the P365, this pistol has a lot of force behind it. It may be small, but it fires like a cannon. When you shoot this handgun, you can actually feel the recoil in your hand. You can also see the muzzle rise as it’s shot. However, this doesn’t take anything away from the pistol’s accuracy and ease of use. Unlike numerous guns of the same size, the P365 is a beast when it comes to shooting from a distance.

Further, you’ll find the P365 extremely effective when it comes to shooting small targets. You don’t even have to spend a notable amount of time perfecting your aim. As soon as you see the target you’re trying to shoot on the pistol’s front sight, then it’s time to shoot. The brightness of the front sight makes it super easy to discern and combined with the smoothness of the trigger action, you’ll be hitting the bullseye of all your targets.

We’ve tried shooting both the P365 and Glock 43 in similar situations to determine the superior pistol, and to our surprise—being huge Glock fans—we felt a lot more confident shooting the Sig P365 than its competitor. We’re not the sharpest shooters out there, but shots that were fairly challenging to make with the Glock 43, were much easier with the P365.

Compared to similar-sized pistols, the recoil of the P365 isn’t significantly flippy; it’s able to make some of the flattest shots in our history. Keep in mind that your mileage will vary based on how effective your grip is. Nevertheless, whether you’re a dead shot or a novice shooter, you’ll find the P365 to be an impressive yet forgiving firearm. Shots that were only possible with duty-sized firearms simply cannot phase this brilliant CCW.


The P365’s capacity is one of its strongest selling points. For the pistol’s size, it’s almost unreal how it’s capable of accommodating 10, 12, or 15 rounds without any problems. Just to put things into perspective, it’s slightly smaller than the S&W Shield which can only accommodate 8 rounds. Just let that sink in for a moment. The Sig P365 completely redefined the standards that make a subcompact handgun.

How did Sig Sauer’s engineers manage to pull off this sorcery? Well, the Pistol Product Manager at that time, Phil Strader, wanted to revolutionize the market of micro-compact pistols, and so he instructed the engineers to start designing a double-stack mag that’s capable of accommodating 10 rounds, at the very least, while making it as small as possible. Based on their design of the mag, the rest of the design process went smoothly.

As we mentioned before, the P365 comes accompanied by a couple of 10-round mags. The first mag flaunts a slight pinky extension, whereas the other has a flush base plate. During our testing, we noticed that we were able to place a good portion of the pinky finger onto the grip. This is made possible due to the undercut as well as other design characteristics; you don’t even have to have a solid grip to use it efficiently.

We tested both the 10-round mags that accompanied the firearm, and we grew to enjoy using the flush base plate mag over the one with the slight pinky extension. If you utilize a 12-round magazine, you’ll notice that the length of the grip will be extended slightly. To put things into perspective, once again, a Sig P365 equipped with a 12-round magazine is still shorter than the M&P Shield.

Having tried the P365 with both 10-round and 12-round magazines, we can safely say that we’re much more fond of the latter mags. There’s absolutely nothing wrong with the 10-round mags, it’s just that the slight addition in grip length when you equip a 12-round magazine makes the pistol feel different, in a positive way, of course. We haven’t tried the newer 15-round magazines yet, but we’re sure they’re as high-quality as the rest.

One thing we admire about Sig Sauer magazines is their remarkable quality. These are sturdy metal-bodied mags that are going to last you a very long time. The only downside is that these mags are pretty costly compared to ones from other manufacturers. Also, we don’t think there are any aftermarket Sig P365 mods as of yet, so whenever you’d like to upgrade to 12-round or 15-round mags, you have to get them directly from Sig.


When observing the Sig P365 dimensions, it’s as accurate as you’d like a gun of its size to be. Like we already mentioned, we’re not the sharpest shooters out there, but trying out a bunch of different loads, we found the P365 to be extremely accurate for its size. We tested the firearm on a fairly confined range. At around 15 yards, we were able to achieve 3-inch groups, approximately. Not bad at all for a micro-compact striker-fired pistol.

With that being said, there are very few challenges that we encountered when shooting the Sig P365 in terms of accuracy, the most prominent one being not able to see much of the target we were shooting at due to the notable width of the front sight post. This was evident because the target wasn’t very far. Aside from that, we’re in love with how accurate the pistol and how shootable and smooth the trigger is. If you can get past the width issue, this is the most accurate 9mm pistol out of the box


Reliability is the most critical factor when it comes to determining whether any product is worthwhile or not. Things are quite interesting with regard to the Sig P365’s reliability, to say the least. Since its release in 2018, lots of respected firearm reviewers have had a lot to say about the P365 in terms of reliability, and what they had to say wasn’t positive, per se. Many seemed to have shared the opinion that the P365 was released too early.

Before we started testing the P365 Nitron micro-compact, we took heed of the different issues that have been noted by other reviewers so that we can examine the righteousness of these claims. We will be covering each of the noted issues in the following segments, but just to give you, dear reader, some peace of mind, in case you don’t feel like reading the next editorial, our experience with the Sig Sauer P365 is primarily positive, all things considered.

Also, we feel the need to point out that the Sig Sauer’s warranty and customer service are amongst the best in the firearms industry, so even if you were to encounter an issue with your Sig pistol, all you have to do is return the pistol and they’ll happily resolve the issue, be it one of the issues we’re about to highlight or an entirely different malfunction. With that out of the way, let’s take a look at some of the reported P365-related issues.

Sig-Lite Night Sight Failures

As we stated when highlighting the Sig P365’s sights, earlier releases of the pistol were attired with Sig-Lite Night Sights, which were faulty sights that couldn’t handle the recoil velocity of the slide. The issue was resolved when Sig decided to replace the sights with their new XRay3 Day/Night Sights. Other reports indicated that the sights were loose in their channels, but it seems like the issue has been resolved by Sig Sauer as well.

Slide and Barrel Peening

Peening is another issue that was associated with the Sig P365. It was reported that it’s a result of the extravagant banging of the pistol’s slide into the corners of the barrel hood. Not only that, but between the locking lug and barrel cam as well. Once again, Sig took the initiative and managed to address the problem. Currently, there are no reports of any peening, which didn’t seem like a major issue in the first place.

Broken Firing Pins

There are numerous documented instances where the firing pins on the Sig P365 were broken. Lots of people believe that the primer drag is the cause of this issue, but we find it hard to believe that considering how sturdy a firing pin is compared to any primer. Sig indicated that this problem was only present in a limited number of P365s. To capitalize on this problem, many companies started releasing stainless steel replacement strikers.

Does that mean you should purchase an aftermarket replacement striker if you intend to buy the Sig Sauer P365? Not at all, as this problem doesn’t seem to occur nowadays. These aftermarket components are intended for pistol owners who are concerned about the problem, regardless of the pistol they own, so it’s not just about the P365. Sig didn’t rest on their laurels and decided to remake the striker to prevent any future recurrence.

Primer/Striker Drag

As we’ve just mentioned, the speculated reason behind the P365’s broken firing pins is the primer drag. Not sure what the primer drag is, exactly? It’s when the pistol’s striker is in direct contact with the primer while the barrel is beginning to unlock from the slide. It’s a common problem amongst most striker-fired firearms that are of smaller size due to the short travel towards the rear that the slide undergoes before unlocking.

If you inspect a larger firearm, you’ll notice that both the barrel and slide remain locked for quite a while, providing enough time for the striker to retract before the barrel starts to unlock. Primer drag, as we said, is no stranger to smaller firearms and doesn’t seem to have a pronounced negative effect. However, the Sig P365 seems to have been the odd one out. This is no longer an issue now, thanks to Sig Sauer’s prompt reaction.

Return-to-Battery Problems

RTB failures were associated with the Sig P365 during its first month of release. This is an issue that’s related only to the first few pistols that were released. We’ve tried a few different models of the P365 as preparation for this review, and we can wholeheartedly assure you that there are no RTB issues with any of the models we tried. It’s speculated that the pistol’s early issues were associated with the utilized ammunition.

Trigger Return Spring Failures

Another notable problem that the Sig P365 seemed to have suffered from is the failure of the trigger return spring. While we didn’t experience this issue with any of the P365s we’ve tested, we’ve seen lots of reports that solidify such failures. As usual, the problems were resolved by Sig. It’s speculated by many, including us, that the failures associated with the return spring were a result of it popping out of its intended position.

Failure to Lockback 

Problems keep piling up for the P365, huh? Well, when it comes to failure to lockback, we’re far from convinced about the legitimacy of the problem, to begin with. We did see a few reviews that highlight the problem, but none of the information disclosed in these reviews was consistent whatsoever.

We genuinely believe that these reviews and their claims of a failure to lockback are pretty much due to shooter-based error rather than a failure in the mechanism.

sig sauer in holster

How can this be a shooter-based problem? If you take into consideration the position of the P365’s slide stop and the size of the gun itself, it won’t be hard to see why shooters wouldn’t feel tempted to ride the slide stop using the thumb of their dominant hand. Why is that a problem, exactly? Because such a small pistol will rotate the slide stop into the shooter’s thumb, causing failure to lockback. It’s quite subtle but highly probable.

Ejection/Feeding Problems

Lastly, it was reported that the Sig P365 suffered from ejection/feeding problems. Having tested the pistol for quite some time, we came to the conclusion that the reported issues were probably ammunition-related. To be more specific, the problem was evident with gun owners who used aluminum and steel-cased cartridges, which happens to be some of the cheapest types of ammunition available on the market today.

We equipped our Sig P365s with brass-cased ammunition, and we’re confident enough to say that we encountered little to no ejection/feeding malfunctions. If you’re worried about such malfunctions taking place while shooting a P365, then we strongly recommend steering clear of cheap steel or aluminum-cased ammunition. This should also apply to all firearms, as cheap ammo can be fairly damaging to firearms.

Sig P365 Variants

After the release of the Sig P365, Sig Sauer quickly capitalized on the firearm’s success by putting out additional models to appease eager customers. In this section of our P365 review, we’re going to cover the different variants of the firearm and conduct a brief comparison between each of these currently available P365 models so that it’s easier for you to determine which one suits you the most. Let’s jump right into it.

Variants Comparison

Sig P365 Base

The standard P365, also known as the Sig P365 Nitron, is the base model for the pistol we’re reviewing today. As a quick recap, this is a sub-compact firearm that’s capable of accommodating 10, 12, or 15-round mags. The P365 Nitron comes equipped with XRay3 Night Sights for improved low-light performance. It flaunts an overall length of 5.8in and has a 3.1in barrel. The pistol weighs only 17.8oz, so it’s pretty lightweight. Further, the standard P365 has a crisp 6lbs trigger and comes with two 10-round mags, one of which being a flush-fitting mag. Being such a small pistol, the Base variant is extremely easy to conceal and offers you an excellent balance between size and capacity. Besides, it’s an extremely reliable pistol that’ll help you carry out accurate shots that are only possible with the aid of a duty-sized firearm. It’s arguably the best concealed carry gun.

Sig P365 SAS

The SAS moniker highlighting this variant of the P365 stands for Sig Anti Snag, which is used to label Sig Sauer pistols with trimmed features. This variant is even smaller and more snag-free than the standard model, as it takes the SAS moniker to the extreme. The side lock, sights, and takedown lever that are featured on the Base variant are gone with the P365 SAS, making it the ULTIMATE model for concealment.

Don’t get us wrong, this Sig Sauer 9mm compact features sights, but not the Sig P365 sights. The SAS’ sights are flush with the slide, and it’s only a rear sight known as the FT Bullseye sight. To strip it down even further or to make it more concealable, both the slide and barrel are ported, which helps reduce muzzle rise, making it easier to control. Aside from that, the SAS model is similar in size and shape to the original pistol.

Sig P365 XL

The Sig 365 XL is the big brother of the standard P365. If you’re into pistols with longer barrels and grips, then you’ll certainly enjoy using the P365 XL. The overall length of the pistol is 6.6in and the barrel is extended out to be 3.7in. This pistol is designed to host a 12-round magazine rather than a 10-rounder. It’s also able to accommodate a 15-round mag. Furthermore, the pistol is equipped with red dot capabilities for increased accuracy.

If you’re not into using red dots, Sig still offers the pistol equipped with their remarkable XRay 3 sights. Considering the pistol’s larger size, you’ll be able to get an extra radius from the sights. The Sig Sauer P365 XL is available in manual and standard safety. If you seek ultimate concealment, this isn’t the variant for you. Nevertheless, the P365 XL does flaunt an excellent size-to-capacity ratio that works for concealment.

Sig P365 Malfunctions

Now that we’ve pointed out just about everything you need to know about the Sig P 365 and its different variants, it’s time to finish off this review by going over the few malfunctions we’ve experienced while we were testing the firearm. For the most part, our experience with the P365 has been pretty positive. The gun ran very smoothly until we tried testing some aluminum-cased ammunition. Federal ammunition, to be exact.

After firing a couple of hundred rounds, double-feeding took place due to failure to extract. We didn’t pay it much attention and continued firing. A few shots later, double-feeding occurred again. Throughout the rest of the aluminum-cased shots, zero double-feeding problems occurred again. However, we didn’t stop there, we grabbed some 124-grain Winchester Ranger-T +P ammo and only one feeding malfunction occurred throughout 700 rounds.

That one malfunction that occurred was a result of the next round diving into the mag. It’s worth noting that we’ve fired tons of brass-cased ammunition and we didn’t encounter any problems. Furthermore, we tried some steel-cased ammo, and we have to say that this is by far the worst type of ammo to use with a P365. In fact, we couldn’t average more than 3-4 rounds for either 10-round or 12-round magazines.

We weren’t quite sure whether or not these malfunctions had to do with the models we had, so we started conversing with other P365 owners to see if they encountered similar issues. It was a 50/50 situation. Some P365 owners didn’t have any issues firing steel-cased ammo, whereas others shared a similar experience to ours. Thereafter, we decided to try some V-Crown and 365 FMJ 115-grain loads for further insight.

gun shooting

Note that both the V-Crown and 365 FMJ cartridges are designed to feel very identical. Why? Well, the whole idea is to practice with the FMJ, which happens to be the cheaper of the two options so that you can get an idea of how the V-Crown loads feel without spending a whole lot of money. Once you’ve gotten familiar with the FMJ’s velocity, recoil impulse, and so forth, then you can start using the more expensive V-Crown JHP loads.

Back to brass-cased rounds, we continued firing until we ran into our very first malfunction after a couple of thousand rounds. To be more precise, it was a legitimate failure to extract. We utilized a Federal Premium 115-grain cartridge during that specific part of the test. We didn’t experience any similar malfunctions after that. If we were to rate the P365 in terms of reliability with average-quality brass-cased loads, we’d give it a 9.7/10.

Once again, we went back to conversing with a bunch of different P365 owners just to assess their experiences with the pistol. This time, however, we were eyewitnesses to their experiences. We’ve witnessed thousands of rounds being shot from numerous P365s, and there were some malfunctions that we’ve witnessed. The thing is, the number of malfunctions we’ve witnessed can be counted on one hand. 

Some P365 owners experienced more malfunctions than others, but even with the one owner who had the most malfunctions, the Sig P365 displayed remarkable reliability that exceeds 99.8%. This reliability percentage could be translated to a single failure every thousand rounds, which is quite an impressive ratio. And compared to its number-one competitor, the Glock 43, the Sig P365 displayed superior reliability.

If you’re worried about the 0.2% that the Sig P365 is missing out on, we’re here to tell you that there’s no such thing as a perfect firearm. It’s completely unrealistic to find a firearm that flaunts 100% reliability. So at the end of the day, the Sig P365 cannot be faulted for a single malfunction that occurs every 1,000 rounds on average. It’s an all-around solid concealed-carry pistol that flaunts mechanical wizardry and superb reliability.


  • Accuracy and Shootability

    We’re yet to see a pistol that’s as small as the P365 display similar accuracy. This pistol can transform a mediocre shooter into a dead shot with enough practice and dedication. It’s one of the smallest striker-fired pistols you’ll ever see, but it shoots just like the big boys. It has proven accurate with a bunch of different loads, so it’s not just a one-trick pony that requires a specific type of load in order to display its full potential.

  • Compact Size and Capacity

    The P365’s size, with respect to its capacity, is a spectacular achievement on its own. It’s a micro-compact pistol that can accommodate 10, 12, and 15-round magazines. If you think 15-round firearms like the Sig P320 or Glock 19 are compact, you’ve got another thing coming. The P365 is so small that it pretty much disappears onto your waist, and if that’s not enough for you, the P365 SAS variant provides snag-free concealment.

  • Extremely Smooth Trigger

    This will come across as an extremely bold claim, but here it goes: It’s impossible to find a small-sized striker-fired pistol that flaunts a better trigger than the P365’s. This is one of the smoothest and crispiest triggers we’ve ever wrapped our fingers around. We love the fact that this trigger breaks in the middle of the stroker rather than at the rear of the trigger guard. This 6-lb trigger breaks before your fingers get the chance to overwrap it.

  • Modular Chassis Structure

    The Sig P320 is one of Sig Sauer’s most popular pistols, so it doesn’t really surprise us that the P365 draws some design elements from its predecessor. It features a serialized chassis that you can remove with ease from the grip module. This means that the pistol will always have plenty of third-party aftermarket components that can help improve its already-impressive performance. It’s also great for those who want two grip modules.


  • Failure to Extract

    There are a number of reported malfunctions associated with the P365, with failure to extract being the most common one. Failure to extract, also known as double-feeding, is when you fire a round and the pistol fails to extract the fired case. This results in the slide continuing to move to the rear in order to pick up the next round but ends up pushing the next round into the empty casing that’s still chambered in the pistol.

    Clearing this malfunction can be quite annoying if it happens often because it requires you to lock the slide to the rear and then strip the magazine completely. Then, you’ll be required to rack the slide a few times, equip the pistol with a loaded mag, rack the slide again, and then put a fresh round in the chamber. Clearing this malfunction, as you can see, is a pain in the neck compared to clearing other malfunctions like failure to fire.

    One thing we’ve noticed is that whenever the Sig P365 undergoes some sort of failure, it increases the frequency of the double-feed malfunction, which is probably because of its sub-compact construction where all components are too close to each other that if a failure takes place in one component, it affects the rest. This problem is common with steel and aluminum-cased ammo, so you’ll probably need to use brass-cased ammo.

    Why is it more common with aluminum and steel-cased ammo? Well, we’re not trying to get into a full-blown discussion about the physical properties of materials, but to sum it up briefly, it might have to do with the modulus of elasticity of both aluminum and steel, which happens to be notably higher than brass’ modulus of elasticity. A high modulus of elasticity translates to slower material contraction, resulting in failure to extract.

  • Magazine Release

    As we keep saying time and time again, we’re huge fans of the P365’s design, but there is one design decision that we’re not fond of, and that’s the design of the mag release. It flaunts a mag release button that has a shape that complements the contour of the grip, whereas its predecessor, the P320, flaunted a flat raised button. Both approaches are fine, really, but we would’ve preferred a combination of the two for more convenience.

    The reason we’re saying this is due to the size of the grip. It’s too small that if you grip it too firmly you might actually press the release button with your support hand due to the pistol’s recoil. In order to prevent this from happening, you’ll have to practice easing the grip of your support hand. This is a probable encounter for virtually all adult hands, and it’s safe to assume that you’ll run into it a few times if you’re new to using the P365.

  • Overly Shallow Grip

    The P365’s grip is too shallow, which is to be expected considering the ultra-compact size of the firearm. Don’t get us wrong, the grip felt fairly nice in hand and we appreciate most of its design aspects, from the contouring to the stippling, but we really think that it would have benefited significantly from adding to the distance between the front strap and the back strap. We’re just thinking out loud, we’re sure Sig had their reasons.

  • Front Sight

    We’ve touched on this in our discussion of the XRay 3 Day/Night Sights. Like we stated before, we’re huge fans of the sights; they’re highly visible in both broad daylight and low-light conditions. However, we can’t help but feel that the front sight is a bit too wide, shortening the distance between it and the rear sight. This results in the front sight filling the notch a little too much. It’s a minor complaint, but we felt it’s worth noting.


All things considered, we think the Sig Sauer P365 is a remarkable concealed-carry gun that raises the bar for other micro-compact handguns. From its exceptional accuracy and shootability to its insane capacity and high-reliability percentage, the P365 is just a work of magic and sorcery. Kudos to Sig Sauer for creating such a small yet impressive firearm. If you’re looking for a defensive CCW, the Sig P365 is right up your alley.
