If sling shots are considered an acceptable non-lethal contact option, I wonder if the same logic would apply to a Sig Sauer P320 CO2 semi-automatic 30 round air pistol that shoots pellets?
Serious question.

It might be useful to wrap a red tape around the end of the barrel in some way to attempt to indicate you are not brandishing a firearm. It also comes in a desert tan color which might appear less obvious and less threatening to the uninformed. I think black is already generally perceived to be the color of an assault weapon.

Muzzle velocity is "up to" (meaning less than) 450 fps. It shoots pellets or steel bb's. I don't know what the effective range might be.
It would be a bummer to get shot for pulling out an air pistol.
