Handgun ammunition consists of cartridges designed specifically for use in handguns. Each cartridge typically includes a bullet, gunpowder, and a primer, which ignites the gunpowder when struck by the firing pin. Common calibers for handgun ammunition include .22 LR, .9mm, and .45 ACP, each offering different performance characteristics and uses. The choice of ammunition can affect accuracy, recoil, and stopping power. Handgun ammunition is used for various purposes, including target shooting, self-defense, and law enforcement. Understanding the specifications and types of ammunition is essential for safe and effective handgun operation.
