Again, just my two cents. When a non shooter (that will never be a shooter) tells me he is buying a shotgun for home defense and ask what I think, I tell him save his money and move to a nicer neighborhoodYou don't need practice shooting a self loading shotgun. Pull the trigger until it runs out of ammo. I can't tell you how many pump gun owners I've seen on quail and pheasant hunts that short stroke the pump guns and hear a click or nothing at all. Home defense only intensifies the pressure.
I have no accurate stats to quote, but Its got to be 80-90% of shotgun owners that will buy one for SD and never put a box through it before storing it under the bed.
I'm also not in favor of a SXS. Only two shots. You need capacity.
