Can we legally own and use any examples of these in CA such as the older C&R models like an old BHP or Mauser Broomhandle? I have never fired a handgun so equiped, has anyone ever doen it or owned one?
IIRC some manufacturers have made models that fall away from the gun once you remove your hand which makes them legal, not sure for CA though.
Some makers have offered them on cap and ball revolver too IIRC, I assume those would be ok for CA? Though you would have to watch for injury to your forearm if you hold the gun certain ways due to the cylinder gap.
Or how about a single action centerfire revolver with a 16in barrel and shoulder stock? I rmember those kits to turn a 1911 pattern pistol in to a rifle also but thse seem CA illegal now.
A Stechkin would be fun and doubly illegal
