Components of Ammunition

Before we discuss the various types of ammunition used by Glock, first, you need to know about the main components of any ammunition, which are:

The Primer

A primer is a small metal cup that contains a chemical compound. When the trigger is pulled and the firing pin hits the primer, the chemicals are ignited. These chemicals then create a small explosion that ignites the gunpowder. The gunpowder produces gases causing the bullet to be forced out of the cartridge and down the gun's barrel.

The Case

A case is what holds everything together. It's made out of brass or steel, and it has a neck and a base. The neck of the case holds the bullet, while the base contains the primer. The case also has an extractor groove that helps extract the spent casing from the gun once the shell has gets fired.

Powder

The powder is a solid propellant used to ignite the gunpowder made out of charcoal or another combustible material. When the primer stricks, it ignites the powder and creates a small explosion. This explosion then ignites the gunpowder, producing gases that cause the bullet to be forced out of the cartridge and down the gun's barrel.

The Cartridge

A cartridge is a self-contained unit that contains all of the components needed to fire a single shot. It includes the case, the primer, the bullet, and the gunpowder. Cartridges are typically made out of brass or steel or made out of other materials.

The Bullet

The bullet is the actual projectile that is fired from the gun. It's usually made out of the lead but can also be made from copper or other materials. The bullet seats are in the neck of the case and are held by a small amount of pressure. When the gunpowder ignites, it creates gases that cause the bullet to be forced out of the cartridge and down the gun's barrel.
