My dad thinks he wants a small pistol. He lives in a large Texas city and becoming more concerned with crime. He used to be a pretty good shot in 1960 and he still gets around reasonably. I'm not too worried about the cost (and this won't be a straw Purchase...I'll find it and take him to the LGS).
we took him to shoot 2 years ago and he was fine. He is not frail but a 16 year old could easily overpower him.

Have any of you found a easy to use pistol (semi or revolver) that might be appropriate for my Dad? Or do you know the right questions to ask? I'm not sure I'm all that objective in this one.
