I'd help WWII bring back 16" barrel

ATF exemption was a recent event (1984?). From 1934 GCA through 1984, fifty year it's illegal to attach stock to pistol in the U.S., unless it's registered. That's history now, if the pistol is exempted in C&R list. Certain rules still apply though, e.g. stock, if not original, must be similar to original one -- that's very subjective, no detail spec.
