True but they also want to outlaw tactical shotguns.
Collapsible stock, pistol grip, too many shells in the magazine, short barrel.
The typical hunting style shotgun is not very useful in cramped quarters such as a hallway.
Those body guards for Michail Corleone when he returned to Sicily, Were carrying short barreled Luparos. I think both were Berettas. They each had a sling.
They are very short and handy since they have no pump or automatic action to add 3 inches to the length.
If they had auto ejectors they would also be very quick to reload from loose shells in your pocket or a pair of shells carried between your fingers.
