A stun gun is a very good choice for self defense purposes, however there are others. If you are intending on keeping something on your own for self defense, then you need to check out all your options. Personally, I enjoy pepper spray as the most effective option, but if you think about it, a stun gun is more incapacitating. By way of example, if just pepper spray were used, there is a probability that this assailant with a gun could get off a shot. That's just one example, but maybe a stun gun is the perfect idea in terms of women self defense.
