I bought a pair from a guy on ebay. Pretty sure he goes by 1911 grip guy. They are a very nice grip and fit great. My brother in law has one of the early S&W perf center 1911s. My grips are very, very similar to his. Side by side the easiest way to tell is I got my grips with a cover pin and a mag well cut. One thing I have noticed is seeing those guns in the shop lately the grips look darker to me.
