I have all the components needed to convert an HK USP Compact into V1 (standard DA/SA config with safety. These parts were removed from a later model USP45 Compact with the 2-piece catch. Parts show virtually no wear. No mods, polishing, etc. I've heard these parts work in all USP's, i.e. 9mm's and .40's, full-size or compact, but not certain. Asking $65 delivered or trade for night sights for P2000.
