Try >>>/k/ instead of /fit/ for this question. I'd sooner recommend learning wrestling because you won't spend the night in jail if you have to subdue a violent fucker.

Guns are seriously overrated in melee combat where knives are much better, but both of them make shit scary dangerous fast. I'd sooner pack mace or shit so I wouldn't go to prison after taking a fucker down or have to worry about his buddies trying to pull a gun on me.

Learn wrestling. It's the ultimate martial art for subduing a violent fucker without spending the night in jail, since it works without hitting people.

>Shoot a knee
This ain't hollywood you stupid fuck. Shooting a knee can still kill a person (it's called bleeding to death) and because it's slow and involves the use of a firearm it can make a situation more dangerous than it was before you fired. If the situation was already placing you in mortal peril then the knee would not be the best target either.
