Home Security Camera's recommendation

...I was doing a little window shopping last night. Mossberg has a shorter barrel 20 gauge pump. Can't beat that for reliability, less recoil, still the pump deterrent and shred multiple bad guys, if needed. Hate she even needs to think about it, or you worry about her for it, but it's the times we live in. Good luck to her and you on keeping her safe, whatever route you take.
