I shoot a bunch of different guns and cals. I've shot a Glock 22 with a drop-in .357 Sig for 15+ (?) years and a .45 P-12 Para Ord. for almost exactly same amount of years (always tried to celebrate a new son/daughters' birth with commemorative handgun & knife---helps you remember when all 3 arrived). Have never had even 1 jam, misfire, etc. with either and both will shoot better than I can take credit for. Also hand load all my rounds for every gun I own(except scatterguns) and am willing to bet this makes a difference. Anyway, trust my Glock and my P-12 completely and don't own a Sig, but they look sweet!
