Due to their lack of protruding hammer, many striker fired pistol designs have flooded the concealed carry market. Manufacturers such as Glock, Smith & Wesson, Springfield Armory all have popular models of striker fired pistols. But, how does striker fire actually work?
To propel a bullet from its cartridge, the gun powder within the casing must be ignited. Centerfire and rimfire rounds have two slightly different means to accomplish this. Both feature primers on the back end of the casing. Centerfire ammo features primer only in the center of the back of the cartridge, whereas the primer covers the entire base of the casing of rimfire rounds.
With either type of ammunition, the rear of the casing must be struck with enough force to ignite the primer, which catalyzes the gunpowder explosion that ultimately propels the bullet from the cartridge through the gun barrel.
