oh sorry what I meant was during a range trip this past weekend, my top pin (where the slide lock lever spring butts up against), started to walk left after about 300 rds. I was shooting a mix of from the bench, to holster to running course of fire. I just pushed it back in and continued.
I've got maybe 5-6k rds thru it so far. first time happening and kept happening, mm,, almost every 50 rds or so.
I'll check to see if I reassemlbed correctly, but there really isn't any brain into shoving the top pin in...insert the slide lock lever, and push in the bottom pin.
