In a never-ending march of evolution, Mossberg continues to improve upon already well-established models.

The 940 Pro Tactical is yet another example of this dedication to improvement.

Can the 940 beat the 930?

Shotguns are based in extremely old technology, but has Mossberg brought the platform into the modern age? I suspected they had, but after testing the latest offering, I was convinced.

But what won me over? Follow along as I walk you through the specs, features, pros/cons, and range observations.

Background

Shotguns have been around since the 16th century and have continually improved in their capabilities. Modern semi-autos are top-notch for their reliability.

Mossberg improved the 940 Pro Tactical over the 930 SPX Tactical, an already impressive gun we reviewed here. The list of upgrades is fairly significant.

Mossberg 930 Tactical
Stiff competition

The buttstock pad feels much improved, providing good grip on the shoulder as well as cushion for recoil. They added an extended elevator and removed the notch that always seems to catch my digits when loading.

In the same area, Mossberg enlarged the loading port by beveling the edges. The improved gas system softens recoil and is supposed to run cleaner than previous versions.

Beveled edges

I love that the barrel clamp now has M-LOK slots so you can mount accessories. It appears to be made of polymer, so continued testing with a sturdy light will be needed to find out how it holds up.

MLOK!

The 940 Pro Tactical uses the Accu-Choke system, but perhaps the best upgrade is the addition of an optics platform. Shooters can remove a plate and install optics with the Shield RMSc pattern, taking ye old fowling piece into the modern era.

Who Is It For?

This is not a hunting gun, and it’s not really a competitive shooter. Mossberg has five different versions of the 940 Pro -- all of which hit those different categories.

This version is tactical and is designed for that application. Anyone wanting to defend their home or attend training geared for these scenarios would be well served by the 940 Pro Tactical.

Fit & Feel

The ergonomics on the Mossberg are improved from the 930. The buttpad is tackier and a bit more squishy for recoil.

The pistol grip is gone in favor of the traditional butt stock. The forend is thinner, well curved, and has more checkering for better grip.

Super bright and easy to track

The comb was raised and comfortable for establishing cheek weld. The front sight is a marvelously bright fiberoptic that looks like a red dot in the full Texas sun.

The trigger was short, had only the slightest travel, then broke cleanly at just about 3 pounds on my Lyman digital gauge.

How Does It Shoot?

I kept all shooting within 25 yards for this test but hit everything I aimed at, whether launching various sizes of shot or firing slugs.

Although I don’t have much practice running a plate rack with a shotgun, I was able to steadily increase my speed using the 940.

It’s surprising just how fast you can empty this gun. The short trigger and overall dampening of recoil mean you can send a lot of love downrange in a hurry.

Don’t get me wrong, recoil is still significant – it’s a 12-gauge. But it is manageable, and even after a day at the range putting the scattergun through its paces, I didn’t feel beat up.

The combined butt pad and gas system did a good job of taming the recoil compared to even the 930 I had on hand.

What Sets It Apart?

The biggest factor setting this gun apart from comparable models is the fact it is optics-ready. The ergonomics are improved, and recoil dampening between the butt pad and gas system also helps.

Overall, the gun has a much more streamlined aesthetic compared to the 930 Tactical SPX.

By The Numbers

Reliability: 5/5

I fed the 940 Pro Tactical a variety of shells, slugs, birdshot, buck, and they all ran. Everything fed, fired, and cycled clear just fine over the course of approximately 250 shells.

Ergonomics: 5/5

In this category, the 940 has clearly improved over the 930. Efforts to clean up the thumb-gobbling lifter, as well as an oversized bolt release button, were greatly appreciated.

Accuracy: 5/5

As mentioned, I hit everything I aimed at. It’s encouraging too that shooters can use different chokes in the gun if they want to stretch out its capabilities.

Customization: 4/5

The barrel clamp’s M-LOK slots show great promise and would allow shooters to bolt on accessories without adding too much to the overall width. Plus, it’s hard to beat being able to mount a decent red dot on your shotgun.

Value: 5/5

Compared to the 930 Tactical SPX, which still has an MSRP of $1,228, the 940 Pro Tactical is slightly less with an MSRP of $1,154. (I've even seen it in a few places for $999.) This is an interesting move for a gun that is arguably more capable and ergonomic.

Overall: 5/5

Upgrades for Mossberg 940 Pro Tactical

Your first upgrade for this street sweeper is a red (or green) dot fitting the Shield RMSc pattern. After that, you may want to add a hardy tactical light to the MLOK up front.

The controls have already been upgraded.

Final Verdict

I absolutely love shotguns and was happy to take a crack at the latest tactical shooter from Mossberg. Don’t get me wrong, the 930 is still an amazing shotgun.

But it was nice to see the influence so many people had in the 940 Pro Tactical's evolution.

Can't wait to see how Mossberg evolves from here

Improved controls, ergonomics, and heightened capabilities with the addition of optics, all at a lower MSRP, is an impressive move!

  • Great info. Looking into shooting some birds here in Texas. I was unaware of the 3 shell limit when hunting. With that in mind, 7+1 really is of no benefit. I do like what you had to say regarding the features of this weapon. Not wanting to hamper the full functionality, any suggestions on a similar with less than 7+1? I just hate to use a plug.
    ...
    • Sean Curtis

      Sure Pete, it's interesting but the price between the 940 Pro Tactical and 940 hunting models is roughly the same. Given that, I'd lean toward suggesting the Pro Tactical since it runs the Accu-Choke System. I know plugs are a pain, but maybe you run it a couple of weeks out of the year with a plug and different choke, then have an outstanding home defender the rest of the year.
      ...
  • Good morning here from Canada, Paulatuk NWT. Does the 940 have a 28" or a 30" barrel
    ...
    • Sean Curtis

      Hi Francis, as tested, the barrel length is 18.5". This is a tactical shotgun.
      ...
  • Hi Sean-

    I am a small guy @ 135 LBS and 5'4".

    I would like to get a Shotgun for Home Défense.

    Will my size put me at a disadvantage with the pump action kind? The semi-auto variety are a lot more $$. Not sure i want to spend $2K for a Benelli M4.

    Thx.
    ...
    • Sean Curtis

      The recoil on gas guns is sometimes better, but training is going to be the greatest benefit when it comes to handling any shotgun. A pump is a great alternative. It's a little slower, but here again, training prevails.
      ...
    • Kenneth

      Get a 20 gauge semi auto. Massad Ayoob told me face to face: “ 20 gauge is nearly as effective as 12 and much fAster for second shot. The coroner cannot tell the difference “
      ...
  • Very nice review! I had a Berretta 1201FP, but sold it during the pandemic for a nice profit, and am in the market for a semiauto 12ga again. Turner's has it on their site for $999 and it has my interest. A few comments about the article: I was also thrown off by the limited ammo statement, limited ammo capacity would have eliminated any confusion, the proper term is damping, dampening is to moisten with water. And lastly, any mention of an a/m pistol grip stock would have been nice.
    ...
    • Mark

      Love this 940 Pro Tactical. The last thing i need is another firearm but i just ordered this one from Turner’s today.
      ...
      • Sean Curtis

        Nice Mark, any feedback on how you like it?
        ...
  • Please explain the Con listed as "limited ammo". Is 3" really that scarce?

    Thanks.
    ...
    • Sean Curtis

      Hey Terry, thanks for your question. Sometimes it's honestly tough to find cons for these products, particularly the more upgraded ones. By listing the capacity as a "con" I'm simply pointing out the difference between it and a detachable magazine-fed firearm. At 8+1, you get much less than an AR-15 at 30+1. I realize the power of those 9 are more substantial!
      ...
  • I think you sold me one. This and the other 940 Pro variants look like Mossberg actually paid attention to what customers want. The thumb safety alone is enough to convince me but with the addition of an adjustable stock that model should be able to be made perfect within a few minutes of opening the box.
    ...
    • Sean Curtis

      That's really the best part of this story, between watching the aftermarket and suggestions from their pros, Mossberg has created products folks want to use. Adding the barrel clamp with MLOK is a great example.
      ...
  • Love my JM930 so this seems to up the ante even more. I've run it against dudes with (admittidely smoother) Benellis, but we all shot about the same times even when swapping platforms...so unless you're a high bidget gun snob, the 940 seems hard to beat
    ...
    • Sean Curtis

      Couldn't agree more, and thanks for providing the performance review compared to the Benelli!
      ...
  • If it is going for $1100, no matter how improved it is, even with the great review; I can’t imagine not paying $200 more for a Beretta 1300
    ...
    • Paul F

      I've got nothing against Mossberg, but my Beretta 1301 Tactical gen2 enhanced is amazing, absolutely no regrets on picking the 1301 over Mossberg or Benneli.
      ...
      • Sean Curtis

        Paul,

        While I haven't tried one out yet, I've only heard great things about the 1301.
        ...
    • Sean Curtis

      Ian, I've seen them on some retailer's websites for $999 but they are often out of stock.
