How would you go about measureing the barrel length of a crack barrel shotgun? Basically to get an exact measurement to indicate legallity lol! I ask because I picked one up that had been cut down to 18in. When I say 18in., it is litterally 18in!!!! I know 18 is legal, but I want to be sure about the measurement in this case.
Also, I would like to find out if I can change the barrel on this thing, and if so, can it be a pistol cal. barrel? .357 for example?
