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being loaded into the chamber, when the bolt "slams" forward (hence the name), as a result of the firing pin having not been retracted into the bolt, or from the firing pin being carried forward by the momentum of returning to battery.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 ...
In 1907, Stevens was approached by John Browning and offered the design of a pump-action, hammerless, take-down, repeating shotgun that would become the Model 520 and 620 shotguns. [19] The Model 520, easily recognized by its distinctive double-hump receiver, first appeared in Stevens' 1909 Catalog #52 and remained in production until 1939. [18 ...
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.
If the barrel, receiver and bolt are not fitted properly, severe and potential fatal problems can arise due to faulty headspace, e.g. cartridge overpressure and case rupture. Threaded barrels are often mounted to the receiver with a lot of torque, and will therefore generally require tools for assembly and disassembly, such as a suitable action ...
Colt Single Action Army hammer at half cock. Half-cock is when the position of the hammer of a firearm is partially—but not completely—cocked. Many firearms, particularly older firearms, had a notch cut into the hammer allowing half-cock, as this position would neither allow the gun to fire nor permit the hammer-mounted firing pin to rest on a live percussion cap or cartridge.
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 ...

Slamfire occurs when the cartridge discharges as soon as it reaches the chamber, rather than waiting in the chamber to receive a firing pin impact when the trigger is pulled. Schematic of an Advanced Primer Ignition blowback operation that works in a similar way to slamfire by striking the cartridge as its moving forward before it is fully ...
