One of the bigger surprises of 2021 was the release of the Smith & Wesson M&P 12 gauge shotgun. S&W has been out of the shotgun game for a long time, and the company didn’t just toss a basic pump-action scattergun into their product line and call it a day. They released a dual tube bullpup pump-action shotgun that traces its lineage to the O.G. dual tube shotgun, the KelTec KSG.

Smith & Wesson’s timing was perfect since tactical shotguns are having a bit of a revival these days with increased concerns over crime and personal defense. The S&W M&P 12 promises a professional-grade pump-action, dual-tube, bullpup shotgun that can keep up with demanding shooters.

The S&W M&P 12 Gauge In Living Color

The S&W M&P 12 is a complicated shotgun. It’s not complicated to use, but it’s one of those guns for which you’d be wise to peruse the manual before taking out to the range. Let’s start from the front and work our way back. The M&P 12 wears a 19-inch barrel that’s threaded for (Remchoke) chokes. Modified and cylinder bore choke tubes come with the gun.

The pump part of the pump-action is M-LOK compatible and heavily textured. S&W wisely includes a heavy-duty forward grip that’s also heavily textured. It’s tough for your hand to slip when working the action with a vertical foregrip that is best described as anchored. It’s not just attached to one M-LOK handguard slot, but seemingly several.

The shotgun’s pump extends rearward a fair bit and houses a set of buttons. These allow you to swap from one magazine tube to the other with a press of the button. It’s quick and easy to switch tubes and can be done on the fly. According to the manual, you shouldn’t switch tubes with the pump to the rear.

Above the barrel sits an M-LOK slotted barrel shroud and an optics rail runs across the top. This makes it easy to add lights, lasers, and obviously optics. The shotgun doesn’t come with any kind of iron sights. For red dots, you’ll need an AR height optic because it’s an inline design much like a AR-15.

The Pistol Grip

On the lower portion of the gun, there’s an ambidextrous AR-15-like safety with a 90-degree throw. Forward of the trigger sits an ambidextrous pump release that requires the user to press it downwards to unlock. The pistol grip comes from the M&P AR line and four interchangeable palm swells to fit the grip to your hand size.

That heavily textured theme follows through to the pistol grip, and it’s almost too aggressive. Almost.

Above the pistol grip sits a pair of load assist levers on either side of the gun. Pressing these levers makes it easy to load shells and makes it possible to admin unload the gun without running the pump.

You don’t need to press the levers to load the gun. They just retract the shell holder and makes it easier, albeit much slower. The gun can hold seven rounds of 2.75-inch shells in each of its dual tubes (14 total) or six 3-inch shells (a total of 12).

Finally, at the rear of the gun, there’s a small button that can be activated. When pressed, you can pull the stock rearward and open up the loading/ejection port. The intention of this device is to allow the user to open up the shotgun and fish out any stuck cartridges in the event of a malfunction.

As you can see, the Smith & Wesson M&P 12 has a lot going for it.

At The Range

Most of the time, I have to add a snarky ‘No, it doesn’t take mini shells,’ to my shotgun reviews. Here, though, I can’t. The M&P12 happily takes mini shells and will hold twenty of them. Mini shells are fun, but beyond plinking they don’t interest me much. A lot of bullpup shotguns seem to have noticeably more felt recoil than standard shotguns. Especially those semi-automatic bullpup shotguns.

The S&W M&P 12 isn’t too bad in the recoil department. It doesn’t feel a whole helluva lot different than any other pump-action shotgun. The M&P 12 weighs 8.3 pounds unloaded, so it’s no featherweight. Along with that mass, the big foregrip and rear pistol grip really help you engage in a good push/pull technique to mitigate recoil.

You’ll feel the bump with each pull of the trigger, but it won’t beat you up. What surprised with was that trigger.

For one, it’s a shotgun. Two, it’s a bullpup (which have never been known for good triggers). As a result, I didn’t expect much. It’s honestly not that bad. The M&P 12 trigger won’t win any awards, but it’s definitely better than expected. It’s got a fair bit of take-up, but it’s light and breaks cleanly. Reset is fairly long.

The shotgun’s pump action moves smoothly and is grit-free. Smith & Wesson did a fantastic job with the pump here. It’s not classic Wingmaster smooth, but it doesn’t feel like there’s a bunch of sand in action.

Loading and Ejecting

Loading the S&W M&P 12 isn’t easy or fast, which is why all of that capacity is such a good thing. Like most bullpups, the M&P 12 doesn’t give you those Instagram-fast reloads. The two loading ports in the rear of the gun are recessed and tough to reach. Speedy tactical reloads, or shoot two, load two, aren’t going to be the norm with this gun.

The rounds eject from the bottom of the gun. This makes it well-suited for both lefties and righties. The S&W M&P 12 does a great job of being a fully ambidextrous shotgun. The controls are all essentially ambidextrous. Bullpups are rarely lefty-friendly, but the S&W M&P 12 doesn’t discriminate.

The length of pull is quite long for a bullpup. (Travis Pike for TTAG)

At least it doesn’t discriminate between dominant hands. Where it does is in shooter size. The length of pull here is over 14 inches, and that’s long. Why they went that far with it is beyond me. This isn’t a clay shooting gun. A 13 or even 12.5-inch length of pull would have been a much better choice for a tactical shotgun. Heck, I’m a big guy, and it feels a little too long even for my knuckle-dragging arms.

Shucking and Pumping

Getting multiple rounds on target with the S&W M&P 12 isn’t difficult. This gun can dish out a serious beating — on its targets — and doesn’t choke. As far as tactical shotguns go, it does exhibit some real strengths. It’s a little over 27 inches long overall, but doesn’t have the NFA penalty. It holds double the ammo of most shotguns and it’s easy to accessorize. Heck, S&W even includes a fancy AR15 case with the gun.

For home defense, it would be tough to beat. Sure, it can’t be reloaded quickly, but if you run through 14 rounds of buckshot in a home defense situation, you likely need a crew-served weapon.

Ratings (out of five stars):

Reliability * * * * *
Not a single malfunction throughout many different loads. High brass, low brass, mini shells, buckshot, slugs, birdshot, and more. Nothing fancy. When I pumped the gun, I knew it would fire.

Ergonomics * * * ½
The M&P 12’s long length of pull is the primary detraction from this gun. Second to that are the slow reloads. Other than that, the ambidextrous nature of the gun makes it an impressive weapon.

Accuracy * * * * *
It’s a shotgun. At shotgun ranges, it’s plenty accurate. With FliteControl, it patterns into one ragged hole at home defense distances. With cheap buckshot, the patterns open up to about 4 inches at 10 yards. Not bad by any means. Oh, and the trigger doesn’t suck, either.

Overall * * * *
The Smith & Wesson M&P 12 shotgun provides an impressive bullpup shotgun. It’s well made, reliable, lefty-friendly, and holds more than half a box of ammo. It might be the best pump action bullpup currently on the market.

  1. Wonder if Keltec’s originality in this market space is enough to sustain them considering the bigger players in it these days.

    • I had the opportunity to shoot the Keltec space-shottie. Will never touch one again. Absolutely horrible ergonomics. This one from S&W seems to be chasing the “what’s hip” crowd instead of opting for reliable functionality.

      I’ll stick with my trusty 870.

      • Saw the double barrel version in a defensive shotgun class a while ago……. neat but would not trust being able to load it in anything approaching a stressful situation let alone under pressure. With that said when it did work look out on that rate of fire. Will also be sticking with 870 or 500/590 for anything that requires reliability.

  2. There was an earlier recall on these for barrels cracking. Not sure where in the process that recall stands. Once the bugs have been worked out. I may consider 1 for a truck gun.

  3. There is just something kinda special about a bull pup. I just saw this in Guns and Ammo TV. It looked huge to me. Although I think I would enjoy a box magazine over dual tubes. But this is certainly not something to sneeze at.

  4. I know a scum sucking whore of an attorney named Geoffrey Silverman of Portland Oregon who got my marijuana bootlegging tenant a free pass for shooting at my son by asserting “12 gauge shotgun? That’s small caliber, isn’t it?”. He got away with this crap because he is married to Columbia County Deputy District Attorney Kim Silverman.

    This S&W shotgun would be perfect for giving this attorney an advanced tutorial on the effects of various types of shotgun projectiles on human tissues. Given the dual feed, you could begin with alternating rounds of birdshot and buckshot then switch to slugs. Given the 14 round magazine capacity, you could demonstrate that a shotgun can be lethal even from a range of 200 yards in spite of the low hit probability.

      • A lot of people smoke marijuana. It has been decriminalized in Oregon. However; production and trafficking of marijuana remains a Federal felony. Having ones’ property misapropriated for a marijuana grow imposes enormous risks of criminal and civil forefeiture liability not to mention property damage and criminal violence. The Oregon Medical Marijuana Program along with the Oregon Liquor and Cannabis Commission are so corrupt that they entered into a criminal conspiracy with the Oregon Marijuana Mafia by issuing address specific grow site and extraction site permits without the knowledge or consent of the property owner.

        If you want to grow marijuana, fine. Just do it on your own property. Don’t shoot at my children in retaliation if I object.

        Also, the State of Oregon needs to teach it’s imbecilic judges that a 12 gauge shotgun is a deadly weapon. It would be helpful if we didn’t have a bunch of TactiCoolFools on this website spewing BS about how handguns and shotguns aren’t deadly weapons except at close range. You people need to learn to understand the math not just punch in entries to an online ballistics calculator.

        • But but but… if you legalize marijuana it takes out the criminal element.

          Just in case. /s
          Hope your son is okay.

        • Darcian can attest to the wimpiness of the 12 gauge, even offering to stand in front of one being fired. He has seen the results documented many times by two unimpeachable sources, Road Runner AND Bugs Bunny.

  5. I know TTAG has their rating system but why is accuracy a rating on shotgun reviews? Even if it’s a Serbu Super Shorty with a 12 in barrel, it all comes down to the choke installed.

    I loved the great detail off all the features and thoughts on them. S&W put a lot of engineering into this polymer beast!

    • Actually, if a shotgun has a shroud or other accessories that prevents a shooter from sighting directly down the barrel, then alignment between the barrel, sights or accessory rail becomes important. Also in traditional pump or semiautomatic shotguns that have quickly removable barrels, the lockup between the receiver and barrel can be to loose to deliver consistent impact centroids. Finally, a sight bead that is not installed at the proper location on the muzzle can cause accuracy issues.

  6. Shotguns are effective based on feel and fast handling. I would much, much rather have the Remington 870, Reminton V 3 Tactical, Ithaca 37, Mossberg 500/590 or Benelli over this thing. I assume it handles similar to the Kel Tec. This thing much be aimed carefully. So we have a long gun demanding careful aiming but with a very limited range compared to a rifle. Kind of like the ridiculous AR type shotguns. If you need a shotgun use a shotgun. If you need a rifle then use a rifle. Another tip- a Remington 1100 set up for 3 gun would eat this think up in a match. But what do I know? Just fifty years of shooting. I own three pump shotguns and the V3 tactical. And three good AR rifles. To each his own.

    • I aim all my guns carefully, long and short. But I can only lay claim to forty years of shooting, so there’s that…

  7. The price of a Glock, a CZ, and two conventional shotguns from the used rack.
    Or a fair AR and a Glock- I could go on.

    Absolutely unimpressed by SW quality. Shield triggers hanging up, which I hope the new 2.0 fixed, and a .45 M P pistol that sheared the magazine release at 200 rounds. Revolvers with the safety lock that occasionally fails and MIM hammers. Make you look hard at Taurus! But Ruger really.

  8. I’d be awfully tempted to just save up a few more hundred for the IWI TS-12 for semi automatic and comparable capacity. Only thing you really lose is the mini shells.

    On the other hand, my chances of actually finding this in a local gun store will be much higher.
