The growing popularity
940 JM Pro in conjunction with famed world-champion shooter Jerry Miculek as a one-stop shotgun platform for beginners and seasoned competitors alike. This 12-gauge semi-auto has a 3-inch chamber, although 3-inch ammo is seldom used in most competitions. The magazine extension holds nine 2-3/4-inch rounds. With an additional round in the chamber, that means 940 users have 10 rounds total ready and at their disposal. With that kind of available firepower, the 940 JM Pro would also make a formidable home defense shotgun. Or, it could double as a snow goose gun during the unplugged spring conservation season, although the short 24-inch barrel may be less than optimal for gunning high-flying snows. A better choice would be Mossberg’s 930 Snow Goose model which comes in white camo with an incredible 12-round magazine extension. The 940 JM Pro comes in two finishes. My test gun came with a blue-hued Tungsten Gray finish on the receiver and bright gold colored accents on the safety button, trigger, bolt handle, bolt release button, magazine tube
extension nut, and extended choke tubes. There is also a MultiCam Black model with black camo on the synthetic stock and forearm and a matte black finish on the controls. The bolt handle and release buttons on both models are oversized for ease of use and quick manipulation, while the safety is tang-mounted in typical Mossberg fashion for easy access by both right- and left-handed shooters. The 940 is powered by a new, redesigned gas system that’s been beefed up over the flagship 930’s action to handle the rigors of competition. Mossberg claims it can go 1,500 rounds between cleanings and still function reliably, but more frequent cleaning is advisable. My test gun got pretty Several of the 940’s internal parts have a nickel boron coating, which also aids cleanup and functioning. The treatment is similar to that found on Mossberg’s 930 and 935 Pro-Series Waterfowl and 930 Pro-Series Sporting semi-autos. The 940 comes with a fiberoptic HiViz front sight for quick target acquisition, even in dirty, although post-shoot cleanup was relatively easy.
of three-gun shooting has spawned some increasingly specialized firearms developed specifically for this sport. For those who don’t know, three-gun competitions involve timed stages set for rifles, handguns, and shotguns. Guns of all three types are needed to participate, hence the sport’s name. Most participants use an AR rifle of some sort, almost always in .223, a semi-auto pistol, often in 9mm, and a shotgun, usually a 12-gauge semi-auto with a magazine extension. That extension is essential to prevent frequent reloads which hinder good times. High-capacity magazines are readily available for ARs and pistols, but not many shotguns come factory equipped with extended magazines. Competitors usually retrofit an extension onto an existing platform. From experience, I know this can be either very easy or extremely difficult, depending on the shotgun model. Thankfully, Mossberg now offers a convenient solution with this year’s introduction of the 940 JM Pro. Mossberg designed its new
