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.
After the trigger mechanism has been released, the tensioned mainspring will drive the firing pin or hit the firing pin so that it is driven. Mainsprings can come in many shapes, such as a cylindrical spring ( Mosin-Nagant , TT-33 , Colt M1911 ), plate spring ( Nagant revolver model 1895, Makarov pistol ) or spiral spring ( Kalashnikov ).
A firing pin and firing pin spring, whose design can greatly affect the lock time of a firearm. Lock time or action time refers to the time interval (often measured in milliseconds) from when the trigger of a firearm is activated until the firing pin strikes the primer, and depends on the design of the firing mechanism. A long lock time ...
The Arsenal Firearms AF2011-A1 is a double-barreled, semi-automatic pistol of Italian origin. The weapon is a derivative of the M1911 pistol and the majority of internal parts including the firing pins, firing pin plates, sear groups, springs, recoil rods, and mainspring housings are interchangeable with standard M1911 replacement parts.

Single-shot actions operate only to ignite a cartridge that is separately set up ("in battery") for firing, and are incapable of moving the cartridge, itself. As the name implies, all single-shot firearms (unless they are multi-barreled) can only hold one round of ammunition and need to be manually reloaded after every firing. Historically ...
Firearms use triggers to initiate the firing of a cartridge seated within the gun barrel chamber.This is accomplished by actuating a striking device through a combination of mainspring (which stores elastic energy), a trap mechanism that can hold the spring under tension, an intermediate mechanism to transmit the kinetic energy from the spring releasing, and a firing pin to eventually strike ...
Compared to a closed-bolt design, open-bolt weapons generally have fewer moving parts. The firing pin is often part of the bolt, saving on manufacturing costs; the inertia of the bolt closing also causes the fixed firing pin to strike a blow on the primer, without need for a separate hammer/striker and spring.
