I'm generally not one to add anything to a shotgun, short of maybe aftermarket slug sights, but that is one fine looking Police Magnum, Chief Brody.
The Police Magnum with walnut is one of my favorite shotguns, the other being an Ithaca '37 LAPD special.
That is what comes to mind when I think "riot gun".
