Apologies but I am not sure what exactly you are asking? You already have a 590, or are you contemplating getting one? If you are wanting to transition home defense to a shotgun, the Mossberg is a great platform. The “Shockwave” 590 would not be my first choice. you Guys are basically just a few years younger than I am so you remember well the years the semi auto shotguns were unreliable. The technology has risen dramatically and semi shotguns now are very very reliable. I would lean towards that if recoil management is a primary concern. There are some great home defense designed semi auto shotguns by Bennelli, and others.
