FM-9 firing pin assembly includes a 2 piece firing pin, firing pin spring, bushing guide and cotter pin.
The FM-9 Firing Pin was designed to be a two piece firing pin for a reason, by separating the firing pin
into two pieces it reduces the stress on the center of the pin, reducing the tendency for a fracture over
the life of the firing pin.
Made from S7 Tool Steel, heat treated to 55 HRC for long lasting performance.
