Looking for a CCW gun for my dad. He's "old" :-) and just had surgery on his right wrist. He has to wear a brace and has limited wrist motion from a titanium "spider" that was screwed into his wrist after the removal of a couple little bones in the hand. Obviously he can't handle any recoil so a 38 special is out of the question. I'm looking at S&W 22's and while I think the 22 mag would be a better choice stopping power wise, I'm not sure the velocity out of a short barrel will be significantly more than a 22 LR... if that is the case, I would tend to lean toward the 22LR... But, if the 22 mag is significantly better for self defense, I think he could handle it.
So, the question: What is better for an old fart with a bad wrist taking into consideration stopping power from a S&W snub nose... a 22LR or a 22 mag?
