Kahr should be able to fix it right. Its pretty basic in design. The down side is the FP spring is strong enough to slam fire the cartridge if, 1) the bolt has not cycled back far enough to hook up the FP onto the trigger sear, but far enough to strip a cartridge out of the mag. 2) the trigger disconector is not tripping the sear back into its up position, there for allowing the FP to move forward with the bolt onto a fresh round. The Tommy bolt face was designed for a fixed FP so even if the FP is protruding "while stripping out a fresh round", it will chamber the round cleanly and possible tap fire the round as the extractor clips over the chambered round. Mind you, this is typically "not" a unsafe malfunction as far as firing out of battery is concerned. The stiff extractor coupled with the 360 deg. cartridge supported bolt face pretty much ensures a non out of battery firing. Other wise, the FA units would have been blown out casing master pieces. How do I know all this you might ask? I was the AO West Hurley gunsmith 81-83 and built more than a couple 27's
That said, I agree with RETRO, if a Fed sees it go full in your hands, it has the potential to destroy your life legally.
