Looks like I was one of the fortunate ones with a 1927 that worked, at least until this weekend. After 5 years of no problems something was bound to happen. Went to the range this weekend and the bolt would lock back in the open position after every round fired. Tried a stick mag & a drum, it would lock using both. I verified that it wasn't the locking catch for the magazine that was hanging it up. I disassembled the gun tonight and everything was right where it was supposed to be. I changed the mag catch out a few weeks ago so I thought I might have put the gun back together wrong
but I didn't. Is there anything else internally that could cause the problem? What about the disconector? What exactly does that thing do?
