AVERAGE hitting 10" at 6m, with pistol from low ready. TRY reacting, hitting that fast with shotgun,from low ready. TRY working a pump, moving over, hitting ANOTHER guy, same range, say, 5 ft apart, in the .30 second in which it can be done (to hit CHEST with the pistol, just hit TORSO with pump gun. 20 ft is a LONG shot in most homes. Most rooms aren't 20 ft, kitty corner, nor will most guys be pressed back into those corners. pump shotgun can't even beat a PISTOL, at typical indoor stuff.
