I’ve pondered getting a shotgun. I suppose it would be useful if you are dealing with more than one bad guy who are standing together in the same general area. Happy with my 9MM but if Harris wins I’m buying more.
I had a Mossberg 500 12ga, but I sold it- I thought it was too much gun for me. Never fired it.
I will als point out that if home invaders have body armor on dumping buck shot at hip/groin area of a bunched up group of home invaders will be devastating in the immediate and the long term.
