I have pump shotguns. One with 20" barrel. They all stay in my safe with my magazine rifles and everything else I've collected over the years.
As far as shotguns go, I've had single shots, sxs's, O/U's, auto loaders and pumps. I guess that about covers every modern shotgun ever made.
I do recognize the utility however but a rifle wins for applications past 40 yards and a pistol wins for close quarters combat (inside your house). Think knife fight.
That leaves 7-40 yds. for the optimal shotgun range.
Probably the reason for the increasing popularity of SBR's and AR pistols. They can do double duty.
I've never seen anyone at my range with a SD shotgun. The pattern board isn't used and is rusting. I have seen some SBR's and AR pistols however.
I don't want to rain on anyone's parade here. If you like the concept of a SD shotgun you should buy one. What you feel comfortable with is probably more important than anything else.
My choice for
one SD firearm for your home would be a Sig MCX in 300 BLK. When there's lead in the air there's hope.
