Here's my problem: When I try to insert the thumb safety, it isn't lining up properly with the hammer and disconnector. The pin that goes through the beavertail goes through no problem, but when I try to insert the small cut out/machined part of the safety, it doesn't seem to line up. When I forced it in, the grip safety jammed and I couldn't go any farther and I had a devil of a time disassembling it again. I have the hammer in the fired position and have tried juggling it around, but that doesn't seem to help. I am trying to insert the safety in the same "almost engaged" position that I disassembled it. What am I doing wrong? I really don't want to go to a 'smith with a "bag gun" if I can avoid it.
