S&W M&P 12: the Smith & Wesson Bullpup Shotgun

The MP 12 bullpup shotgun is a 12 gauge pump-action designed, S&W says, for home protection. Released just this morning, the M&P 12 is not the first Smith & Wesson shotgun, but it is the first in many years (and their first commercial bullpup design ever).

Like its handgun and rifle predecessors, M&P stands for “Military & Police”.

The M&P12 is a 12-gauge pump-action with a 3 in. chamber and two independent magazines. Total magazine capacity is 12 x 3-in. shells (six/6 per tube) or 14 x 2 3/4 in. (seven/7 per tube), and there is a push-button magazine selector to switch between the two.

A reciprocating cover with a release button provides the mechanism for clearing damaged shells, and an assist button on each of the magazine tubes is provided to assist in loading and unloading.

Previous Smith & Wesson Shotgun Models 

Some previous S&W “scattergats” include:

· The AS Assault Shotgun, a magazine-fed select-fire shotgun reminiscent of the M16

· The S&W Model 1000 semi-auto, manufactured in Japan by Howa Machinery and available in both 12- and 20-gauge. This one dates back to the 70s and 80s; don’t conflate it with the S&W 100 Series, those came out about a decade and a half ago (q.v.). 

· The Model 3000 manual action (i.e. pump) shotgun. Likened to an “improved Remington 870”, it was also made by Howa, also in 12- and 20-gauge configurations. 

· The S&W Elite Series, a break-open sporting shotgun design manufactured in Turkey. 

· The SW Model 916, a rebranded shotgun design originally produced by the Noble shotgun factory as the Noble Model 66. The Model 916 was available in a couple of different versions, including tactical and takedown, but unfortunately like the Model 66 before it consistently suffered reliability issues. In fact, the 916 was later voted one of the worst modern shotguns of all time, though S&W evened the scales back out with the Model 3000 (a design that itself spurred an improvement on the 870 by Remington).
