From Mossberg . . .

Mossberg has released the newest member of its 940 Pro family of 12-gauge shotguns: the optic-ready 940 Pro Tactical 8-shot autoloading shotgun. Based on Mossberg’s cleaner-running and redesigned gas-operating system, the 940 Pro Tactical delivers ease of operation, reliability, adjustability and performance-driven features including optic-ready receiver; oversized controls; M-LOK compatibility; stock adjustability; and an 18.5-inch barrel with interchangeable choke system.

Like all 940 Pro shotguns, the 940 Pro Tactical has corrosion-resistant internal parts and finishes including nickel boron-coated gas piston, magazine tube, hammer and sear. The durable gas system is compatible with factory-manufactured 2.75 and 3-inch shotshells; provides for faster, more reliable cycling; and can run up to 1,500 rounds between cleaning intervals.

To maximize functionality, the 940 Pro Tactical is loaded with performance-driven features starting with receiver cuts to accept the direct mounting of micro-dot sights (Shield RMSc footprint). Direct mounting of the optic provides for proper eye alignment and quicker target acquisition when shouldering the gun. A cover plate is included for when an optic is not mounted.

Receivers are also drilled and tapped for the option of adding rail-mounted optics. The 18.5-inch barrel features a matte finish and is topped with a fiber optic front sight. The barrel is threaded for use with interchangeable AccuChoke choke tubes and the gun comes with a Cylinder choke tube. An enlarged and beveled loading port, elongated, pinch-free elevator and bright orange anodized follower were configured for ease of loading. The knurled, extended charging handle and oversized, ergonomic bolt release lever provide for positive manipulation when loading. The extended magazine tube allows for a 7+1 round capacity with 2.75-inch shells and the barrel clamp features a sling swivel stud plus dual-sided M-LOK compatible-slots for the addition of accessories.

Completing the 940 Pro Tactical is a user-adjustable length-of-pull synthetic stock with a range of 12.5 – 14.25 inches and adjustability for drop at comb and cast with the use of incremental stock shims. The synthetic forend has a slim profile; and both stock and forend feature Mossberg’s signature aggressive texturing for a secure grip and black matte finish. A rear sling swivel stud is also installed.

Mossberg set the standard for defensive shotguns with its family of 500/590/590A1 pump-actions and now the optic-ready 940 Pro Tactical autoloader joins the family, loaded with features that enhance its durability, ease of operation and functionality.

  1. Saw the James Reeves TFB video on this yesterday and immediately fell in love. The shotgun looked great too 😉

    Joking aside, this is on my wish list. I’ve “needed” to add a tactical shotgun to my repertoire, but the price of decent semis kept me away.

    • If you can find ranges/classes that allow it barricade shooting, reloading while moving, and reloading while keeping the shotgun shouldered and having someone randomly call out fire while reloading are great skills to develop. Even just reloading while looking at the target only is useful to work on (and a bit slow to start if you are not used to it).

    • Asking for a semi-automatic shotgun to run mini-shells demonstrates a profound lack of understanding of how a semi-automatic shotgun functions.

      If you want to run mini shells, get a pump gun.

      • If manufacturers believed you, we’d still be living with semi-auto shotguns that only fired “high brass” shotshells.

        First shotgun makers developed semi-autos that you could adjust for full power or lower power loads, now any serious manufacturer has semi-autos that easily handle a mix of ammo types without needing adjustments.

        For a manufacturer to build a semi-auto shotgun that can use mini-shells would not bean overwhelming challenge if they felt there was enough market. BUT you’d probably need to run either all-mini or all-regular ammo, there’s no way current technology would support mixing mini-shells and regular shotgun shells through a semi-auto.

        The real question is whether Mossberg sees a significant market for a 940 Pro that can handle mini-shells. Personally I’d expect to see a 940 Pro Shockwave sooner (to compete with the Remington TAC-13). Once that happens, some custom gunsmith will figure out how to make it handle the mini-shells.

    • I think it’s called the SRM 1228…bullpup design with 4 tube mag that holds 7 in each tube that rotates…not sure which company makes it.

  2. This moved to the top of my list. I don’t yet have a semi shotty. We’ll see what prices it actually goes for.

    • Saw the Reeves video too. Que the “muh Beretta” or a $2000 shottie I carried in I-Rak is better. Eventually getting a semiautomatic shotgun. And it ain’t gonna be a caliphate gat…

      • I have a benelli m4 and a mossberg JM930 and to be frankly honest the JM930 is more user friendly. I have shot both in competition/classes and the biggest difference is the M4 will run even though it is dirtier but we are talking 300 rounds plus. Home defense or personal defense situation, you won’t have a problem.

        • Thank you, that does clear up most questions I would have and does give the mossberg the edge over the M4 even with my primary store being a dealer of them. Be a while before I buy another shotgun with the 870 rustington refinished and running well but great info for budgeting.

  3. Ohhhhh, TACTICAL!! If I buy it, I’ll de-age at least 20+ years and become a square jawed partially bearded muscular stud muffin ready to take on commies! Please tell me more. Surely there’s a place to call or click TODAY!!

    • I think you’re gonna need a coupon for 20% off on a full sleave tatoo as well. As for me, im gonna see if that can be imported into the occupied state of Californis. If so i will order one today.

  4. It looks like a nice shotgun. All the Mossberg I firearms owned were reliable. That’s #1. But, if it’s a shotgun the target better have feathers on it. Otherwise, rifle, handgun, maybe SMG. Just me.

    • When you do not have silly laws restricting classes or features on firearms you can buy/own I do agree with you. When SMG (even semi auto versions) are basically impossible and any semiauto rifle is a scifi horror feature shotguns quickly become a viable option.

    • I agree. but in reverse order. SMG, tactical handgun, AR-carbine/sniper. Everything you need for anything, Nothing you don’t. And to ‘Safe upstate female’, Shitguns are never a viable ‘option’, unless it’s the only game in town. Want to know why? Ask me.

    • Gad, I’m to drunk right now but I’m going to have to call you up one of these days and find out why you dont think a shotgunm is worth a fck for killing people. :>)

  5. Well done (Again) Mossberg !
    But this doesn’t help me at all. I’m past my prime, and I NEED a semi-auto 20 gauge (2, in fact, b/c one for my daughter). I don’t need your Turkish crap shotties with the crossbolt safety ! I NEED a Mossberg 920 , with the safety where it oughtta be !
    I’ve spoken to reps at your NRA convention booths in 2015 and 2019, BEGGING for this favor.
    So far, no dice. Do I need to bribe somebody ? I’ll go as high as $6.48 and Write you a free last will to whosoever will accommodate me.

    • Gregolas,

      I second the request for 20 gauge.

      Sure, if you want to shoot #00 buckshot loads, then 12 gauge is the way to go. If you are satisfied with #1 buckshot or intend to shoot slugs, then 20 gauge is the way to go.

  6. Well that’s a pretty cool shotgunm, I kinda like a wood stock though. When you go to bashing somebody’s head in with a plastic stock it’s not as good as wood .

  7. Mossberg needs to up production. Sure I can get the 590a1 retro on gunbroker for 12-1300 but it should be around 800 retail. I just missed getting one from kygunco a few weeks back for 799.

    I was lucky enough to finally get my hands on 940JM late last year so I’ll make do with that as far as the 940. Now if I could only get some of that $25 federal #8 100 round boxes at Walmart again I could be busting some clays.



    • Honest question, would an AR or lighter rifle cover most of what you need better or is it weight as well as recoil that is the issue?

  9. Listing @ $900$, but no one has the “tactical” type extended magazine guns in stock. Definitely something to look into if one is into practical shotgun use.
