I just had a visit from my dear sister. Fun was had. Being the family gun guy we ran through my collection of pistols to see if any were appropriate for her use in her country home. Not a chance. Due to a combination of age and arthritis she can neither safely or effectively use any sort of real pistol. I include a .22 S&W M&P 22. Just jacking the slide and getting her hands around the grip were a no-go on that.
I said "let me research tasers". So, I need to do that. They seem a viable choice for outside the home use. However, tasing some dude and her leaping from a window in retreat, while acceptable tactics, doesn't seem to be in the cards.
So, now for the home as castle. Any recommendations on a .22/.22 mag rifle that is reliable, light, compact, and needs minimal strength to chamber a round for a "house gun"? (I don't think even .30 carbine is a viable choice here.) I certainly haven't shot everything out there, hints? (Just read the PS-90 posting and the "Old Man's Gun" concept was mentioned, I thought I would throw this out here.)
