Some of the police, seen in the recent college riots, appear to be firing shotguns in the direction of the miscreants. Those are surely something commercial....any thoughts on what??
Understand the reasons for the OP's question, which don't include two legged varmints.
My problem; we all have been schooled to not point a gun at anything without a really good reason.
I'd have a hard time making that transition, even if the gun was loaded with something, theoretically, 'less than lethal'.
It's certainly part of the reason that our war games blank adapters blocked the muzzle of our M16s, making it mighty sure nothing was getting out of the barrel.

ETA- when teaching our gun safety course, I began the second hour by pulling out a pot-metal 1911, and promptly breaking rules 1, 2, and 3. The students were supposed to critique what I was doing wrong, and they did. It felt really wrong to point the fake gun at the students.
