It may more technically be called a "pistol grip shotgun" by many, but it's sold as a pistol and it shoots shotgun shells, not rifle or pistol calibers. Thus it's a shotgun pistol, or conversely a pistol [ as per the 4473 ] in a shotgun caliber. It's highly unlikey he would be jumping through the hoops to bring it if it was simply for plinking.
