Editor’s Note: The Smith & Wesson M&P12 utilizes a bullpup design to deliver high capacity in a short, maneuverable package. Its dual magazine tubes are able to accept six 3-inch shells or seven 2 3/4-inch shells each and also have the ability to use mini-shells. This shotgun also features the ergonomic M&P grip, which includes interchangeable backstraps. Large, ambidextrous controls and downward ejection make this shotgun suitable for both left and right-handed users.
