Many years ago there was a moron who cut a set of double barrels down to the end of the fore end. He must have extended his left hand too far because he shot the ends of two fingers off to the first knuckle when he fired it into the ceiling. So after firing his gun he dropped it and clutched his wounded hand, the liquor store owner produced his own gun and held him until the police came to arrest him. They did make a detour to the emergency room. That was back in the early 60's when shot guns were more common in robberies than today's 9mm semi automatics favored by gang bangers everywhere.
