I can think of a few specialized uses for this gun that it could do better than most.
1. Snake gun. If you need to blast a snake or small animal at close range, .410 is better than pistol caliber shotshells. Maybe you need to kill a Coon in the attic but you don't want to blast a hole in the roof. You get the idea anyway.
2. Anti-carjacking gun. Like someone said, this would be perfect at close range against a carjacker or mugger.
