43. Model 1887
Modern Warfare 2
Call of Duty games are known primarily for their realistic-ish take on warfare and weaponry (well, they used to be, at least). That makes the Model 1887 something of an enigma; Modern Warfare 2 multiplayer was positively plagued by run-and-gunners defying the laws of physics by sprinting around at full tilt with one of these suckers in each hand. And considering it's a lever-action shotgun from 1887, it was way too effective.
