I have owned this Springfield 1911 Stainless Mil-Spec for a good few years now and it has been great. I had a Pistolsmith Guild member install the flat, checkered, main-spring housing which also eliminated Springfield's ILS. He also installed the aluminum match trigger. Grips are exhibition grade walnut, supposedly from Culina (I got them in a trade deal). Stainless Allen grip screws and magazine are from Wilson Combat. This gun has been at least as reliable as my other 1911, a Colt Series 80.
