Built for Speed, Reliability, and Performance
If you’re looking for a shotgun engineered for fast, smooth shooting in competition or high-volume range days, the Mossberg 940 JM Pro Tungsten delivers. Designed with direct input from world-renowned speed shooter Jerry Miculek, this 12-gauge, semi-automatic platform is tuned for performance right out of the box.
Why We Like It
The 940 JM Pro isn’t just built to run — it’s built to win.
- Optimized for Competition
Designed around the needs of top-level 3-gun and action shooters, this shotgun features an extended 9-round magazine tube, a fast-cycling gas system, and a design that accommodates quad loading with ease. - Smart, Shooter-Friendly Features
A generous loading port, elongated elevator, and bevelled edges all come together to make loading under pressure easier and more forgiving. This platform was made for shooters who demand speed without compromising reliability. - Optics Ready
The receiver is cut for Shield RMSc-pattern optics, so you can add a red dot straight from the factory without a custom gunsmithing job. It’s a perfect blend of old-school muscle with new-school tech. - Balanced Length, Built to Last
The 24-inch barrel offers great balance and follow-through while staying nimble enough for competitive movement. Chambered in 12ga with a 3-inch chamber, it cycles reliably under pressure and handles a wide range of loads with ease. - Compatible with Briley Chokes
The 940 JM Pro takes standard Briley chokes, giving you flexibility in patterning for everything from close steel to longer shots on the move.

- Competitive 3-gun and action shooters
