so requiring 3 guns is the bunk. There's no reason to own a shotgun, for defense needs. If the pistol aint enough, the rifle aint too much! A suppressed, shorty AR is a lot more to the point than any shotgun. Indoors, the pattern spread of buckshot aint enough to be (enough) of an aid to hitting to make up for the horrible blast and flash, ruining your hearing and your night adapted vision. Nobody practices enough with slugs to be anything like good enough with them. People who are being shot at use cover, man. A guy who's head on prone to you, wearing a helmet, aint very succeptable to buckshot, beyond about 20 yds, given standard 9 pellet 00 and a riot barrel. So the shotgun is inferior to the sound suppressed AR inside 5 yds and beyond 20 yds. what makes you 'think" that the range will be what you need it to be? :-) The odds are not high enough to justify spending the time and money on a gun that handles so differently from your rifle.
