Mossberg 85174 940 Pro 12 Gauge 3" 5-Round Shotgun

The Mossberg 85174 940 Pro Waterfowl 12 Gauge 3" 4+1 28" is a semi-automatic shotgun engineered for serious waterfowl hunters and tactical operators who demand reliability in harsh, corrosive environments. Built on Mossberg's proven 940 platform, this model combines the speed and ergonomics demanded by law enforcement and military personnel with the specialized design required for extended field use in wet, salty conditions. The 28-inch barrel delivers superior patterning at typical hunting distances while maintaining the handling characteristics operators expect from a modern shotgun.

At 11 lbs, the 940 Pro Waterfowl manages recoil impulse effectively without sacrificing pointability or sustained rapid-fire capability. The patent-pending receiver cuts accept Shield RMSc pattern micro red dot sights directly, eliminating the need for aftermarket adapters and ensuring consistent sight height and zero stability—critical for low-light conditions common in early-morning waterfowl operations. Internal corrosion-resistant components, including boron-nitride coating on key wear surfaces, resist saltwater oxidation and extend service life dramatically compared to conventional shotguns. The 3-inch chamber accommodates modern waterfowl loads while maintaining the 4+1 capacity that balances firepower with magazine-fed reliability.

This platform suits hunters operating in coastal environments, saltmarsh systems, and high-humidity regions where standard finishes fail rapidly. Law enforcement and military units conducting amphibious training or coastal operations benefit from the sealed internals and corrosion-resistant treatment. The optic-ready design supports rapid target acquisition in low-light dawn and dusk hunting scenarios, while the semi-automatic action reduces fatigue during extended field operations. Installation of compatible Shield RMSc micro sights requires no gunsmithing, and the standard Picatinny rails support industry-standard accessories for customization.
