Then I ask them this question:
Are you going to buy the gun and then practice with it,,,
I mean practice enough that you know it better than you do your car?
If they say no I then recommend a revolver,,,
If they say yes I tell them to buy either, depending on their personal likes.
This is great advice. When I still lived with my parents, I cant tell you how many times that when me or my father would leave the house we would have to show my mother how to work a semi-auto pistol since she was alone. No matter how many times we showed her it just never stuck because she didn't have much interest in guns or learning about them, she finally said to get her a 12g pump action shotgun.
