Just talked w/ the guy that originally owned the gun today... he said that he only put 200 rds through it.. and he bought it new. So the gun only has 300 rounds through it total. He stated that he never had a single issue with the gun.. So I believe that it's very probable that I may have been hitting the slide release w/ my thumb during the shot or something like that. I totally disassembled the gun today, cleaned and lubed it a bit more.
How far do you guys normally take down your guns when cleaning them?
