I always figure in a self defense situation I might get just one shot at stopping the threat, and I really doubt I will have time to take the perfect shot. If all I had was a 380 I suppose I would be glad I had it, but really I feel better in my mind with something that starts with a 4. Not saying I don't carry a 9mm on occasion but I do prefer a .40 or .45. And no, I wouldn't want shot with even a BB gun either. Who would?
