Also have you ever noticed that the bad guys can fire off a thousand rounds without hitting anything, but a hero can pop off a round over his/her shoulder on the fly and hit 9 out of 10 shots. Additionally, heroes in movies can take half a dozen rounds and keep on fighting, but bad guys die instantly if a bullet merely parts their hair.
You shouldn't pack a gun for self defense unless you know the reality of how a situation might happen, and you're planning to use it. If you use it, it won't do any good unless you shoot to stop the threat of an attack (i.e. kill). I think most people don't think it through that far.
