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.

The component that holds the firing pin and extractor is typically the bolt in a firearm. The bolt is responsible for chambering the cartridge, locking it in place, and facilitating the firing process. It contains the firing pin, which strikes the primer of the cartridge, and the extractor, which removes the spent casing after firing.
