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.
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 ...
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.
Second, the gun's striker-firing mechanism is locked in place by an extension bar linked to the trigger; the striker cannot move unless the trigger is depressed. Third, as with most pistols, a firing pin block actuated by the same extension bar prevents the pin coming into contact with the primer unless the trigger is pulled to clear the block.
Hammerless weapons were initially accepted with some hesitation because the hammerless guns were manufactured with a locking bar, which secures the trigger only and not the firing hammer. Hammerless weapons, such as the Climax Safety Hammerless Gun, was manufactured with a locking mechanism that locked the trigger and featured a strong block ...

Some military firearms are designed to fire from an open bolt condition to avoid the unintended discharge of a chambered cartridge cooking off in a gun barrel heated by firing previous cartridges. Activating the trigger of such firearms releases the spring-loaded bolt to move forward stripping a cartridge from the magazine into the chamber.
Unlike the rest of the M&P pistols, the M&P Bodyguard 380 is not striker fired. It is a traditional double-action-only hammer-fired pistol intended for personal protection, concealed carry or as a law enforcement "back-up" handgun. Some models incorporate a manual safety. [4]
