Even during ammo shortage, a 12 gauge is an extremely versatile weapon platform and ammunition is always cheap and available. A used Remington 870 goes for $150 at a pawn shop and during times of crisis, one need not be concerned about the legal ramifications of sawing it off to be portable and wieldy.
In sum--get a used 12 gauge, .00 buckshot, and hacksaw.
