First, I think a double action handgun is out. i seriously doubt she has the strength to pull the trigger, much less accuratey. I also seriously question her mindset to flick off the safety on a single action and she won't have the strength to rack the slide. My Grandfather who looked great, was an active guy and very experienced with guns bought a Hi-Power and was unable to rack the slide w/o trouble. you also have to worry about mindset. Is she willing to use the weapon w/o hesitation when it matters? Rember she is scared to death and old, she is not thinking clearly. I think it is generally a bad idea, it could turn a very bad situation where she is hurt imto getting killed. get her a dog, a good alarm, and ask the neighbors to look out after her.
