mizer67 Posted December 22, 2011 Share Posted December 22, 2011 I'm having issues getting primers to light in my M&Ps. They only run near 100% with Federals. Win SP light off pretty good, and CCIs are the worst with 3-5% FTFs. I've tried switching reloading presses, going from a Hornady LNL to a Dillon XL650, but the problem persists from old press to new press. Extra power striker springs from Speed Shooter Specialties seem to help, but my guns still don't run 100%. While it's possible it's operator error, my other striker fired pistols run 100% even with CCIs (Glocks / Wather PPQ). I'm running factory springs in two M&Ps and an extra powered striker spring and Apex FSS in another. I'm using factory recoil springs. Does anyone know of someone that makes an extended firing pin for M&Ps, or of someone that can modify a factory one? Or something else I can look for to completely eliminate light primer hits?
