A firing pin or striker is a part of the firing mechanism of a firearm that impacts the primer in the base of a cartridge and causes it to fire. In firearms terminology, a striker is a particular type of firing pin where a compressed spring acts directly on the firing pin to provide the impact force rather than it being struck by a hammer.
Firearms designed to discharge as the bolt closes may have a fixed firing pin or a firing pin which moves forward by inertia as forward motion of the bolt ceases when the cartridge is fully chambered, while more conventional firearms are designed to prevent the firing pin from impacting the primer until the trigger is pulled. Some unintentional ...
A firing pin block is a mechanical block used in semi-automatic firearms and some revolvers that, when at rest, obstructs forward travel of the firing pin, but is linked to the trigger mechanism and clears the obstruction to the pin just before the hammer or striker is released. This prevents the firing pin from striking a chambered cartridge ...
The firing pin must travel a short distance, creating a short delay between the user pulling the trigger and the weapon firing, which generally decreases accuracy. However, in an electronic-firearm, an electric current instead of conventional mechanical action is used to ignite the propellant which fires the projectile.
Firing pin: The part of a firearm that strikes the primer, discharging the round. Flash suppressor or flash hider: A device that is attached to the muzzle of a firearm, that lowers the temperature at which gases disperse upon firing.
A rimfire firing pin produces a notch at the edge of the case; a centerfire pin produces a depression in the center of the primer. Rimfire ammunition is so named because the firing pin strikes and crushes the base's rim to ignite the primer. The rim of such a cartridge is essentially an expanded and flattened end section of the case, and the ...

A slamfire is a premature, unintended discharge of a firearm that occurs as a round is being loaded into the chamber, when the bolt "slams" forward (hence the name), as a result of the firing pin having not been retracted into the bolt, or from the firing pin being carried forward by the momentum of returning to battery. Similar to a hammer ...
