Firing Pin

A firing pin is a component of a firearm that strikes the primer of a cartridge, initiating the ignition process and causing the firearm to discharge. It is typically a small, cylindrical metal pin that is spring-loaded and located within the firearm's breech or bolt assembly. When the trigger is pulled, the firing pin is released and propelled forward by the spring, striking the primer with enough force to ignite the propellant and propel the bullet out of the barrel. The design and function of firing pins can vary depending on the type of firearm, but their primary purpose is to initiate the firing sequence and ensure reliable ignition of the cartridge.
