I was field stripping my G20L to clean it after a range trip, and I noticed some daylight between the bottom/forward part of the locking block and the frame. Also the top of the locking block isn't flush with the frame either. I disassembled it, put in new pins, and it's still the same. Hopefully I just never noticed this before, but is this normal? I know pics would help, but I don't have any right now. It still functions perfectly, I just want to make sure everything is as it should be before I start throwing parts at it. I'm just hoping it's not a frame issue.
