Mossberg 940 Pro JM 12 Gauge Semi-Auto Shotgun 24" Barrel 4+1

The Mossberg 940 Pro JM delivers Jerry Miculek-approved performance for competitive shooters demanding speed and reliability. This gas-operated semi-automatic shotgun features competition-focused enhancements that reduce reload times and improve target acquisition in high-pressure scenarios.

What Makes This Different

Unlike standard sporting shotguns, the 940 Pro JM incorporates Jerry Miculek's competition insights with oversized gold controls for faster manipulation under stress. The optic-ready receiver accepts red dot sights without additional modifications, while the adjustable shim stock system allows precise fit customization. The tungsten gray Cerakote finish provides superior corrosion resistance compared to standard bluing.

Key Features

• Optic-cut receiver machined for direct red dot mounting
• Oversized gold bolt handle and safety for enhanced visibility and operation
• Adjustable shim stock system with multiple length-of-pull configurations
• HiViz TriComp front sight with interchangeable light pipes
• Extended choke tubes included for versatile shot patterns

The gas-operated action cycles 2¾" and 3" shells reliably across various loads from light target rounds to heavy waterfowl ammunition. Competition shooters benefit from the reduced felt recoil and faster follow-up shots, while hunters appreciate the versatility across different game types. The 24-inch barrel length balances maneuverability with ballistic performance for both clay sports and field applications.
