Worlds smallest shotgun with 3.5-inch shells (VIDEO)

Most of us will never be able to own a sawed-off shotgun due to the regulations and permits required to own one. This video shows a guy who took his sawed-off shotgun to the extreme.

The video is over 16 minutes long, with many different rounds tested. The best one comes at the 5-minute mark when he uses the 3.5-inch shells.
