I've got two:
-- Mossberg 500 12 ga w/20-inch barrel, w/compensated muzzle brake
-- Maverick 88 12 ga w/18.5-inch barrel, stock
Both are 5+1.
That said, I don't usually keep them "at the ready", but in the gun safe. My nightstand HD gun is whatever I carried that day, usually a CZ 75D PCR 9mm (14+1) or a CZ75BD 9mm (16+1).
