I think this is going to take some research at the range.
Most of the suggestions have been good but it's an empirical question.
I see several threads:
1. The heavier 38SPL/357 with lighter loads
2. A 22 revolver
3. A 380, depending on it's recoil.
Trigger pull is a problem. The SW 22 revolvers have a heavy DA pull.
I'll through in another one. I read about folks with weak hands being able to manipulate a SA revolver and liking it's light trigger pull. One can get them easily in 22, 22 Mag, 32, 38/357. Yes, you have a slower rate of fire without practice. It's a suggestion. I have a Ruger SS Bearcat that is real easy to shoot and cock.
I think the person in question just as to try before buy.
