Yup, a shotgun. And difficulty hitting your target depends on what your loaded with (slug or shot shell). And you’ll hit your target just the same with a rifle. Will you be as accurate as aiming down the sights? Certainly not. Will you hit your target center mass? Oh yea unless your eye hand coordination is real off. And the original argument was that pistol grips make you more accurate than firing a weapon without. There’s still rifles and other long guns without pistol grips used in service. If this were true of pistol grips then we’d retire these guns out of national security.
