bear in mind this comes from someone in a country where we don't have guns for HD

what about a regular SbS? in a .410 and with as short of a barrel as possible it will be nifty as hell and as close to 100% reliability as possible.
with practically onlyone mechanical thing for her to worry about, just close it and it is ready, get one with ejectors and with minimal training she could reload, less intimidating for any friends or family that could see it aswell
