I have a Star BM with the common problem of a broken firing pin (no, I didn't dry fire it). It was the longer non-inertia type. The new firing pins are( of course) the shorter inertia types... Top, is the original broken pin, notice the retaining pin notch. Lower is the new pin: Problem is, the notch in the newer pin forbids enough rearward play for a sufficient hammer contact- it doesn't stick out enough from the rear of the slide. Is there a fix for this, or is there no option besides finding the non inertia firing pin? Is it safe/ possible to modify the new pins?
