Shotgun Evaluate: The Mossberg 940 Professional Waterfowl

Mossberg’s long-time motto, “Extra gun for the cash,” clearly guided the event of the 940 Pro Waterfowl semiauto. By packing the 930 platform with options designed to enhance its reliability, Mossberg gives a gun to compete with semiautos costing way more. Improved gasoline system elements and boron-nitride coatings enhance the gun’s reliability and prolong the time it’s capable of run between cleanings.

Mossberg had tried making gasoline semiautos with out a lot success till 2004, when the 935 appeared. A strong 3 ½-inch 12 gauge, the 935 was made to be a price on the expense of versatility: It was meant for 3- and three ½-inch shells solely. Mossberg wanted one other gun to fill out the road, and the 930, which was a 3-inch model of the 935 made for two ¾- and 3-inch shells, joined the lineup the next 12 months. Just like the 935, the 930 shared the highest security typical of Mossberg shotguns, and it had a number of plastic elements to save lots of prices, which is widespread amongst many shotguns now however was much less widespread within the early 2000s.

The 930, like many lower-priced semiautos, has its followers and its detractors. Which camp a 930 proprietor falls into relies on their private expertise with the gun. Some by no means had an issue and cherished it; others, not a lot. In 2020, Mossberg labored with professional shooter Jerry Miculek to construct an improved gun that might face up to the pains of 3-gun competitions. The 930 had already discovered some acceptance within the 3-gun world, and, in actual fact, Mossberg had already launched a Jerry Miculek 930 Professional. The corporate made sufficient adjustments to the 930 to advantage a complete new title, and the 940 was born. The primary 940 was the JM Professional, a devoted race gun. Recognizing that waterfowlers, too, would respect the enhancements in reliability discovered within the 940 JM Professional, Mossberg added a 940 Professional Waterfowl and Professional Snow Goose. At present, the 940 lineup contains the JM Professional, the Professional Waterfowl, Professional Area. Professional Snow Goose, Professional Turkey and Professional Tactical.

When the 935 first got here out, a pal who labored for Mossberg informed me they’d checked out many competing gasoline semiautos as they designed the gun, particularly the Winchester Super X2. The similarities between the 930/935 and the Tremendous X collection are largely evident within the composite spacer tube that serves because the hyperlink between the gasoline piston and the bolt. And, the obvious distinction between the 930 and 940 is that tube. On the 940, the previous plastic tube has been changed by a lighter-weight, vented anodized tube. The vents within the tube enable gases to flee as an alternative of funneling them again into the motion the place they will trigger fouling to construct up. The result’s a gun that stays cleaner and runs higher and longer. As well as, a number of inside elements (the gasoline piston, journal tube, hammer sear, return spring tube) are boron-nitride coated to stop corrosion and the return spring is stainless-steel. There’s additionally an anodized journal spring follower for smoother feeding, and there are drain holes within the inventory in order that if water does get in, it may possibly get again out with out rusting the recoil spring tube.

On the surface, the gun has Cerakote on all steel surfaces to withstand rust and abrasion. The camo artificial inventory has detachable spacers on the butt to permit length-of-pull adjustment, and inventory spacers enable some adjustment of drop and solid. The 28-inch barrel comes with prolonged choke tubes and a fiber-optic bead. And, to make the gun simpler to deal with with chilly, moist or gloved fingers, it has an enlarged bolt deal with and launch.

How We Examined the Mossberg 940 Professional Waterfowl

The 940 Professional Waterfowl was among the many guns we tested throughout the September teal season at Pintail Hunting Club in Texas final fall. We handed weapons off as greatest we might within the mornings as teal swarmed our decoys. Within the afternoons we shot all of the weapons as a lot as doable at Pintail’s clay vary. We additionally examined every gun for level of affect, and we sample examined them with looking hundreds, too—particularly Federal  1 1/8-ounce, 1550-fps a great deal of 2 shot, a highly regarded duck load. We additionally weighed the gun and examined its set off pull with a digital gauge. We weighed the gun at 7 ¾ kilos with a 5 ¾-pound set off pull. The 940 Professional Waterfowl was flat-shooting, with a 50/50 level of affect. With a Modified choke in place, it shot a 75-percent sample at 35 yards.

How the Mossberg 940 Professional Carried out

Dealing with and Ergonomics

As a reasonably heavy gasoline operated semiautomatic, the 940 Professional Waterfowl does a great job of tamping down felt recoil. The gun cycled properly for us, too, working with gentle goal hundreds in addition to 3-inch duck hundreds. The oversize bolt deal with and nearer button and the enlarged loading port make the gun straightforward to load and unload. The 940 does have a distinctly muzzle heavy really feel. It’s the type of gun that doesn’t really feel nice once you decide it up within the retailer, however the weight helps make it steady-pointing and smooth-swinging within the subject. The 940 inventory has sufficient drop and a skinny comb that matches a wide range of individuals and the shims spacers make nonetheless it extra adaptable.

Workmanship and Aesthetics

With its olive Cerakote steel and TruTimber camo inventory and forend, the 940 Professional Waterfowl appears to be like each bit just like the duck gun that it’s. It has the look of a strong workhorse, and whereas Mossberg has made the transition between the forend and the receiver flush in an enchancment over the 930, the 940 nonetheless lacks the modern traces or excellent match and end of a higher-end competitor like a Browning Maxus II. At half the worth, how might it? The plastic piece that forestalls the forend from wiggling appears to be like low-cost, as does the plastic security. It’s value noting that one of many nice pluses of a Mossberg is that there are a ton of aftermarket elements accessible, together with some slick, user-installable tactical safeties so you possibly can clear up that a part of the issue inexpensively.


As a 3-inch gasoline semiauto that may deal with a wide range of 2 ¾ goal and looking hundreds, the 940 Professional Waterfowl can serve plenty of completely different capabilities. With its near-8 pound weight, it will make a strong gun for sporting clays, the place that weight helps soak up recoil and {smooth} your swing whereas the improved gasoline system ought to assist hold it taking pictures. Likewise it will be a great gun for doves, and the drilled, tapped receiver means you possibly can mount a scope or pink dot for turkeys or predators. You might add {a magazine} extension for snow geese, dwelling protection or 3-gun competitors. It might be a heavy gun for carrying within the uplands.


We skilled no failures of any type with the 940 Professional Waterfowl. It cycled 3-inch looking hundreds and a couple of 3/4- inch goal hundreds with equal reliability. Now that Mossberg has added the brand new vented spacer tube they declare the gun can go 1500 rounds between cleanings if want be. We didn’t get an opportunity to place 1500 rounds by it with out cleansing, however the gun did shoot a number of hundred rounds for us with out cleansing and with out a drawback. The boron-nitride coating inside elements, the anodized follower and the stainless return spring in addition to the Cerakote end, ought to all assist this gun face up to the powerful environments the place waterfowlers chase geese and geese.


At $1,092, the 940 Professional Waterfowl sells for a whole lot of {dollars} lower than 3-inch semiautos from Beretta, Browning and Benelli and is priced a lot nearer to weapons just like the Tremendous X4 or Beretta A300, but it has corrosion-resistant options these weapons lack. The 940 Professional Waterfowl’s improved reliability make it an excellent worth in waterfowl gun that may pull double obligation as a goal, turkey, and dove gun as properly. The Professional Waterfowl does value $300 greater than a camo waterfowl mannequin of the 930, however in your further $300 you get improved biking, extra weather-resistant options, an adjustable-length inventory and enlarged bolt deal with and launch button, which is a variety of upgrades.

What the Mossberg 940 Professional Waterfowl Does Greatest

As its title suggests, the 940 Professional Waterfowl is a waterfowl gun, and all its corrosion-resistant options imply waterfowl looking is its greatest use. It may be put to any objective you possibly can use a 3-inch looking gun for, though it’s heavier than you would possibly choose for an upland or run and gun turkey gun. In its pure setting of the waterfowl blind the 940 will shed water like a duck and hold working significantly better than the 930.

What the Gun Does Worst

At 7 ¾ kilos, the 940 Professional Waterfowl is a heavy gun by at this time’s requirements, and there are significantly better decisions for shotguns to hold within the uplands or to sling over your shoulder for a day of strolling the turkey woods. Clearly in the event you imagine 3 ½-inch shells are a necessity for waterfowl or turkeys, you will have to step as much as the 935 Professional Waterfowl, which lacks a number of the superior options of the 940.

Last Ideas

Mossberg’s 940 Professional Waterfowl matches squarely into the corporate’s custom of worth and innovation. The boron-nitride-coated elements, stainless spring, inventory drain holes, and extra all contribute to creating the 940 as weather-proof and dependable as the fundamental 930 platform will be. It’s a cumbersome gun and will not attraction to some because of its weight, nevertheless it’s a strong alternative, and a sensible choice for left-handed shooters who can use the highest security simply as simply as proper handers can. The improved gasoline system ought to assist the gun cycle reliably and make it a sensible choice for bad-weather duck and goose looking.
