My wife is a bartender and works late with drunks. She isn't comfortable carrying a gun and i'm not gonna force the issue. i don't want her to carry something she's not comfortable with. Not sure if OC spray is legal to own/use here in wisconsin. just haven't heard. I know that tasers are legal. With that being said, is there a type of taser that is better or worse than another? is there a good place to buy one? do i need to get a special permit or background check to get her one? We both are getting our CCW permits soon.
