My Norinco 1911 has always been a little rough in the slide movement, and I've decided I want to fix that. The first culprit, I think, is the crazy amount of machine marks on the inside of the frame where the spring rides.
Can I safely grind/sand/polish these down without refitting anything? What's involved for rebluing after? What else could help stop the 'grindy' slide movement?
