Hi, I just acquired a 659 which had an issue with the metal stop that the slide release lever pushed against. I took the grip off and noticed that the search pin is sunk flush against the grip and it's protruding a bit on the other side. So can I tap this back out with out disassembling anything? I ask as the sear pin on my 745 is loose enough to be moved with my fingers while this one can't be moved with just my fingers. Thx!
