Frank's right though. Most people who "buy a gun for protections" seldom if ever practice with it. I personally blame it on the movies.
How many times is there a scene where the heroine, who never liked guns, grabs a snub-nosed revolver that a perp has dropped, and takes out a guy at fifty yards on a rooftop? That or something very similar. It gives the impression that a gun is all powerful and can hit anything at any distance even while moving. When that is all a person is exposed to in the way of guns of course they feel they don't need to practice. (Or for a lot of guys it's a macho thing, "I can shoot a gun. Why should I practice.")
