You can never have enough 12 gauge slugs alternating with 00 buckshot to pile them up higher and deeper. There’s a reason the German’s didn’t like us using shotguns in WW I.
I know but for home defense I like my system. If it takes more than six buckshot I do have the 9mm with 1 in chamber and 15 in mag and a second 15 round mag ready to spin. My abilities with all my weapons in close quarters are more than efficient. Don’t need no fancy Bulldog type shotgun.
