  1. I was present for a case where a new semiauto pistol did, in fact, fire without the trigger being pressed. It was a new 1911, my buddy was clambering a round (and I was watching the gun like a hawk, because, well, a gun was being loaded right next to me), and as the slide slammed home, it went off (brutally massacring a pile of Time-Life coffee table "Old West" books on the floor my friend was pointing at, sending a Black Talon through the books. On examination, we found there was a stack of contributing events - the firing pin spring was slightly short compared to a new Wolff spring or the nearly new Colt spring in my 1911 and the firing pin miked a skosh longer than a Wilson Combat example I had for comparison. Our suspicion is that Norinco (who built the pistol) may have been using tolerances a bit on one edge of the acceptable range, because they probably tested all their guns with Chinese produced ammo... which at the time would all be produced with the typical ComBloc harder primers than typical US civilian production.
