Striker-fired guns, which are becoming more common, have no hammer, but they have a striker that is used as a firing pin instead, while many guns that do have hammers, such as revolvers, they are available with the hammer shrouded or with the hammer spur bobbed off.
From the top: striker-fired, linear hammer with free-floating firing pin, hammer-fired with free-floating firing pin, and hammer-fired with integral firing pin. 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.
An internal hammer cannot be accessed manually during operation. Pistols and shotguns in particular, which have an internal hammer may be referred to as being hammerless. [7] A striker is a type of firing pin operated by the direct action of a spring rather than by a hammer striking the firing pin. Striker-operated firearms lack a hammer.

The pistol is blowback operated and striker fired. [3] It came with a six-round magazine. [4] A 2001 Bureau of Alcohol, Tobacco, Firearms and Explosives publication warned that the pistol is "extremely dangerous" when dropped, with the "potential for serious injury", due to an insufficient gap between the trigger bar and the sear.

Striker-fired pistols, on the other hand, do not have a hammer, so the only way to return the trigger to its longer pull (safer) state is by means of a decocking or detensioning lever which actually releases the tension in the striker's spring without allowing firing pin full travel and internal safeties disengagement (such as the firing pin ...
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 ...
Most modern firearms are designed to not be capable of firing when significantly out-of-battery. As such, a firearm that is out-of-battery typically cannot be fired, which is why this is a type of firearm malfunction. A dangerous situation can occur when a chambered round fires when the firearm is out-of-battery (called an out-of-battery ...
