Someone I used to know in the army is now in SWAT and he mentioned this device. It basically just shoots a fire hose of pepper spray as a non lethal in more urban environments when you want to be really restrictive with shooting. It makes sense to me but I haven’t really done any formal training since I got out and this device is totally a new concept to me. I also can’t seem to find it anywhere. I need some practical advice for this geezer. I’d be willing to put in a few range days a month if it meant I could really up my options but I’m not even sure if it’s legal to own considering I can’t find it anywhere.
