Picking The Right Self Defense Products

My girlfriend gets pretty nervous driving long distances by herself and going out at night with her girlfriends. I’ve been trying to get her to get a CCW permit to carry a handgun, but she doesn’t really feel comfortable around guns and she doesn’t think she would be able to use it if the time came. I’ve been showing her several different self defense products and she has been interested in a few of them. I think she’ll end up carrying a nice taser and some sort of mace-like spray.
