+1 to that, I run an STI Sentry in 9mm with factory ammo all day, never had an issue with the Tripp mags and the metalform mag that it came with, this is the first 1911 i can say has run 100% out of the box (I have even had a Nighthawk that had an issue though that may have been because I was testing too light of a recoil spring). I have 2 friends that i shoot with that have Trojans neither 1 was flawless out of the box with Tripp mags, the other was running the dawson precision mags and he has been happy with it. sorry you are having issues with it I would definitely say it is the exception and not the norm.
