My mother-in-law lives kind of out of the way and is worried about a break-in when she's at home and my father-in-law is working. Dad has a pistol for self defense and a 12 ga. shotgun, but she has never touched them. She's older and somewhat slight so I'm hesitant to teach her the shotgun and the pistol is an old school revolver that I doubt she could pull the trigger on, much less handle the recoil due to arthritis. What do you think about a .410 ga. loaded with home defense rounds for her? A little Mossberg pump loaded with 000 buck or something like that?
