I bought the marvel 22 conversion for my 1911's and have had 0 problems with it. the first day I fired 800 rnds from it which would have paid for the kit 2x over if they had been 45 acp. Fire 45's after training for accuracy with 22's. the 45 kicks and the 22 doesnt.
BTW a "duty trigger" in a glock is often +/- 7lbs, factory is around 6 lbs or so. My SW1911 is set at 5lbs. If I dont pull the trigger it wont go bang. ND's happen when either equipment or people or both break. My 1911 safety off is merely a hammered glock. I still have a drop safety and a grip safety preventing an ND. That is actually more than a Glock has. If both those safeties break, I still have to pull the trigger to go BOOM. Merely a matter of perceptions of safety or lack thereof.
