A firing pin is a small, elongated metal component typically shaped like a slender rod or pin. It is designed to strike the primer of a cartridge, igniting the gunpowder inside. Firing pins can vary in size and design depending on the firearm, but they generally have a pointed or rounded tip at one end and may feature a cylindrical body. In some designs, they may also have a spring mechanism to facilitate the striking action.
Like it says, the firing pin rotates as the action cycles.

To check if your firing pin is missing after disassembling a firearm, first inspect the firing pin channel for any obstructions or damage. Compare the firing pin assembly with a schematic or reference guide for your specific firearm model to ensure all components are present. If the firing pin or any associated parts are absent, you may notice an incomplete assembly or unusual gaps where the firing pin should be located. Additionally, you can consult the manufacturer’s manual for detailed diagrams to confirm the presence of the firing pin.
