A friend of mine made these two shotguns for home defense. They are legal sawed-off shotguns and don’t count as an SBS(short barreled shotgun) because they still retain a legal length barrel and overall length. They are both single shot 12 gauge shotguns, one is an Iver Johnson and I forget what the other is. There is actually a pretty long history of people cutting down single barreled shotguns, bellow is Clyde Barrow’s.
The recoil is a bit jarring, I had the pleasure of shooting both of them and pretty much had to clamp my forward hand on the barrel so as not to get smashed in the face by it.
