It probably wasn't "sawed off". Anyone with any knowledge of shotguns knows that sawing off the barrel of a pump-action weapon wouldn't save a whole lot of space, as you still have the length of the action and the tubular magazine (can't saw them off, you know). It was more than likely a an 18-inch barreled riot gun, like a Mossberg or Winchester. Those dumba**es in the media know nothing about guns, so they probably just used the term "sawed off" because it has more shock effect.
