I would shy away from semi-autos unless the little wifey is an experienced gunman. Too many problems can pop up in a life threatening situation. The .38 special hammerless wheel gun is my all time favorite for the new shooter. If it doesn't go bang when you pull the trigger, simply pull the trigger again. With +P and +P+ ammo, along with the franagibles available, the .38 special is a formable close quarter self defense weapon for any man or woman.
