"Developed in the mid 1990s ... It was the first truly high-capacity shotgun"
Perhaps he should Google ' Street Sweeper ' from the late 1980s.
Now that you mention it, I believe that Ian has done a video about the Street Sweeper, too. He didn’t have much good to say about it. I think it originated in South Africa, too.
A shotgun so “dangerous” and evil that the BATF decided it was a DD.
Street sweeper, maybe, but room sweeper for home defense, you don’t get much spread at distances under 15’. At 15’, my old Remington 12ga semi auto with an 18” (legally shortened) barrel put a 1” hole in a refrigerator door. I don’t know what the spread of shot would be at 15’ for shorter barrels down to say 6”. I suppose stopping power at close range is a plus, but having to reload manually is not.
