My one and only shotgun is a 20 gauge pump.
If I were to use it for home defense, I would, and the only thing "non sporting" about it would be that it would be wearing an 18.5" cylinder-bore "slug barrel" that is made for deer hunting, but I have no intention of hunting deer with this shotgun. The short barrel with its wide-open choke is to make the gun more useful for close-quarters combat.
P.S. I suppose I would prefer to have a tactical flashlight, like you have. I used to have such a set-up, but right now I don't. If I think I need a weapon with a light, I'll grab the SKS with a 3 "D" cell Mag-Light attached.
