Several years ago I did the 9mm conversion ( think C&S) barrel and a few small extractor / ejector tweaks, IIRC, for one I owned and 1 my buddy owned. His was a practical and mine all blued. That was the hot ticket then. These make for the best 40 S&W platform, imnsho. But I'm a definite H-P guy, and this is begging for a good home for Christmas.
