Reddit reviews JPX 4 Shot Compact Pepper Spray Gun

i'd recommend carrying a weapon. maybe something nonlethal or less than lethal if you don't like guns or knives. I've heard very good things about this, though it's quite expensive. stuff like karate just isn't that helpful in a street fight. Even a little keychain pepperspray that isn't old or one of the weaker variants is good. just spray and run like hell.
