940 Pro Waterfowl

The 940 Pro Waterfowl addresses the primary vulnerability of earlier gas-operated shotguns by introducing a thoroughly redesigned system tailored to filthy, cold-weather duck blinds. Mossberg engineered the gas piston and internal cycling components to run up to 1,500 rounds between detailed cleanings, relying heavily on corrosion-resistant boron-nitride coatings across the piston, magazine tube, hammer, and sear. It is built directly for hunters who push heavy steel shot through freezing rain, brackish salt marshes, and muddy layout blinds without wanting to strip and oil their firearm after every single outing.

In the blind, the gun exhibits thoughtful, field-ready ergonomics. Both the charging handle and bolt release paddle are significantly oversized, allowing reliable manipulation when wearing heavy insulated or wet neoprene gloves. The loading port is beveled and enlarged to eliminate snag points when thumbing cold 3-inch shells into the tube. A full set of stock shims and length-of-pull spacers comes in the box, giving hunters the ability to quickly dial in cast, drop, and reach to match bulky late-season layers.

Tipping the scales around 7.8 pounds, it is not built for chasing grouse through timber, but that substantial weight actively dampens the stout recoil of magnum steel payloads. While inertia-driven rivals like the Stoeger M3500 offer simpler takedown and weigh less, this gas system shoots noticeably softer during high-volume decoy shoots. Positioned against midrange mainstays like the Beretta A300 Ultima and Winchester SX4, the 940 stands out for its hard-wearing internal plating and glove-friendly controls.
