Bullet Proof Firing Pin Stops. Most firing pin stops are cheap, mass produced, stamped parts, but they're not Bullet Proof either. A Bullet Proof firing pin stop is fully machined from super tough bar stock steel with great care to radius all corners resulting in a part that is many times stronger than a standard firing pin stop. A quality firing pin stop should fit snuggly in place, therefore this part does require minor fitting to your particular pistol for a perfect fit.Stainless

Fitting
Is nessesary fitting it so that it fits
Response from Chuck- Yes, I would say all of the high end gunsmith parts we sell need to be fit. Especially the firing pin stop to the slide and extractor.
