Wonder if any of you have had this problem I've just experienced with a Browning 1911 .380 ? Gun ran fine for about 200 - 300 rounds, then started hanging up with any ammo you ran through it. Then, all of a sudden when I put a mag in and loaded the chamber with a live round, it wouldn't shoot. Gun "locked" up. You could pull the trigger and the hammer would fall, but wouldn't fire the round. The thumb safety was "locked" in the fire position and would not move to the "safe" position and the slide was "locked". You could not pull the slide back. Hammer would cock and fall when the trigger was pulled, but would not fire the round.
