Firing Pin Stop, STI

The STI firing pin stop is available for fixed sights or cut for STI/BoMar adjustable sights. It is manufactured out of blued 4140 steel. Both styles are available for 9/38/40 calibers and 45 ACP.

Note:  STI has discontinued the sale of aftermarket parts.  As we run out of styles/calibers they will no longer be available.  Check out the Brazos firing pin stops instead.
