i just like single Acton guns(that kind of why i had got the hawes federal marshal) and i love the falling block guns to. I have something to ask and i might sound dumb but i am going to ask anyways. I saw some guns that are for cowboy action shooting and one is the HOWDAH HUNTER PISTOL in 20x20GA and the other is the JB custom mare's leg saw off rifle. Are these legal guns?
