Just my thoughts on home defense.... 3 main concerns. #1 Safety, in the event a child gets hold of it. #2 Stopping power. Something that will put an intruder down. #3 Residual damage. High powered rifles and pistols are out ! Too much residual damage, bullets penetrating walls etc. 20 gauge shotguns with buckshot are good choices except trying to keep them handy and loaded creates a safety issue. My choice is a revolver, 380, 38, 357 etc. My favorite is the Judge Defender revolver loaded with buck shot or the “home defense” rounds. My trick to safety with a revolver is simple.... leave the chamber on the rotating side of the barrel empty. If a child actually has the strength to pull the trigger the firing pin will land on an empty chamber. You know that but nobody else does. JMO
