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.
Advancements in microscopic stamping have led to a push for the inclusion of firing pin microstamping. [32]: 16 The microstamp is etched onto the firing pin and is transferred to the cartridge during the firing process. Each firing pin would have a unique serial number allowing investigators to trace casings found at a crime scene to a known ...
The United States National Research Council released a report in 2008 that endorsed the investigation of microstamping as an alternative to ballistic markings.It had concluded that a national database of ballistic markings is unworkable and that there is not enough scientific evidence that, "every gun leaves microscopic marks on bullets and cartridge cases that are unique to that weapon and ...

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 ).
The greater the chamber pressure, the more rapid throat erosion occurs. This is compounded by rapid firing, which heats and weakens the steel. Trigger: A mechanism that actuates the firing sequence of a firearm. Triggers almost universally consist of levers or buttons actuated by the index finger.

When World War I era machine guns were being tried for use on aircraft, the Lewis gun was found not to be usable with a gun synchronizer for forward firing through the propeller, due to its firing cycle starting with an open bolt. Maxim style arms fired with a cycle starting with a closed bolt, and since the bullet firing from the gun started ...
