I thought about one of those 1911 carbine conversion kits but didnt want to risk getting locked up over it. That maybe different as you are changing to a carbine and then back to a pistol.Perfectly legal to own.....does'nt change status of handgun as there is nothing that changes your handgun.....I've been pulled over in 3 states with my 10.5 with brace....the cops loved it and it was'nt questioned by anyone......There's enough BS to paranoid about.
Other than that idea (I once had for a few moments) I am pretty much a traditional gun type guy. Just keep it longer than 16 or its a pistol has all ways been my practice. I dont see much use in having a rifle cartrige firing pistol.
Think I might be able to pass off a bolt on stock for by peace maker as a pistol brace? Always wanted one of those.
