I have run @ 7000-10,000 round through a 1911 single stacker, S&W 45 acp, havent shot it in 2 seasons and before I start (limited 10/ CDP) having problems on the range I am looking for a complete reliability and spring change out. check firepin, extractor the works. I want to change its sights to fiber optic with an adjustable rear, front grip strap checkering, and its S&A mag well beveled to match the grips, then some reblueing.
