Non Lethal Force options for personal protection?

Anyone here have any experience with using non lethal force against possible aggressor(s)

Pepper Spray, Tasers, kubotons.

Even this kind of thing looks good. But limited range.

 

I recently had an experience with 2 aggressors. I had my 9mm and I’m in 2nd Amendment friendly state, no permit required as long as you got no felony’s you can carry concealed.

Both aggressors immediately backed off once they realized what I had but I’d of liked to of had something non lethal to give them as a parting gift.

 

I never pulled my 9mm, had it holstered under my jacket, but these 2 inbred trailer trash turds figured it out when I unzipped my jacket and reached for it they immediately started backing up and I knew I couldn’t legally spray them both with bullets since they were retreating so I had my hand on it but they never saw the barrel. But they were still talking trash calling me names as they’re going backwards and I’m thinking what I wouldn’t give for a good can of bear spray capable of a long range spray. If I shoot them I could end up in prison, but non lethal pepper spray or whatever, I know the cops around here won’t kick up much fuss over a couple losers that are clearly drunk getting anything non lethal.
