What does the firing pin do?

The firing pin plays a crucial role in the operation of a firearm. Its primary function is to strike the primer of the cartridge. When the trigger is pulled, the firing pin is released from its rested position and moves forward with force. Upon striking the primer, it creates a small explosion that ignites the gunpowder within the cartridge. This ignition produces gas pressure that propels the bullet out of the barrel.

This process is essential for the firearm to function properly; without the firing pin’s action on the primer, the ammunition would remain inert, leading to a failure to fire. Understanding the role of the firing pin is fundamental for anyone learning about firearms, as it emphasizes the importance of the firing mechanism in the shooting process.
