What makes a primer ignite?

Upon being struck with sufficient force generated by the firing pin, or electrically ignited, primers react chemically to produce heat, which gets transferred to the main propellant charge and ignites it, and this, in turn, propels the projectile.

How do firing pins work?

The firing pin strikes the primer, causing it to explode. The spark from the primer ignites the gunpowder. Gas converted from the burning powder rapidly expands in the cartridge. The expanding gas forces the bullet out of the cartridge and down the barrel with great speed.

The typical firing pin is a thin, simple rod with a hardened, rounded tip that strikes and crushes the primer.

What is the difference between a striker and a firing pin?

The most visible difference between striker-fired and hammer-fired pistols is the lack of a hammer. In a striker-fired pistol, the firing pin does not have to be hit to strike the primer of the cartridge. With a striker-fired pistol, pulling the trigger to its maximum pull releases the firing pin itself.

How do firing pins break?

A firing pin is usually well hardened to take repeated firing and contact with the primer to initiate the ignition process, but over time they can become damaged by loose brass filings, fouling or harsh use, so that the end of the pin can be reduced in length, thus not reaching as far forward as usual.
