Taurus 709 slim. The mag won't stay in. All it takes is a bump against the gun and of it comes.
Colt 6920. Machine marks inside and outside of it. Chamber was a mess also it was a single shot for the 1st 500 rounds or so. Fire a round. Put a rod in the barrel to knock the case out then load another round and repeat. Colt told me then that there was nothing wrong with it and it was normal.
There's nothing like the fact that you can take educated professionals with everything on the line and add a little booze and they act like juniors in HS.
