KS-23, because I am obligated to suggest it out of my autistic obsession with it.

Some drunk slavs took a bunch of failed AA cannon barrels and thought "Da, this will work" then rigged an upscaled shotgun frame to it and called it a "riot suppression device".
Holds 4 massive shells that come in BIG SLUG, buckshot, tear gas, rubber/plastic, and even muzzle grenade launcher flavors.
It's the deagle of the shotgun world.
