Sig MPX Recoil Spring

Recommended Posts

Which recoil spring rate is everyone running? Stock? Reduced power? 

Mine is a GenII, has been stone reliable, Lancer handguard, ILWT ejector springs, TACOM buffer/spring, upgraded BCG from Sig.  Been running stock recoil springs but thought I would play with some reduced rate springs to see how it runs with my CO 9mm loads (BBI 125 TC, 3.7gr Sport Pistol, 1.100 OAL, about 140PF).  Thought I would see what others experience has been :cheers:
