Mossberg 940 Pro JM 12 Gauge 3" 9+1 24" Semi-Auto Shotgun - Optic Cut, Black Multicam

The Mossberg 940 Pro JM is a 12 Gauge semi-automatic competition shotgun built around Mossberg's proven gas operating system and developed in collaboration with legendary 3-Gun champion Jerry Miculek.

Featuring a 24" vent-rib barrel backed by a 3" chamber, this autoloader delivers a 9+1 capacity through its extended magazine tube and is engineered to run up to 1500 rounds between cleanings. The Tungsten Gray optic-cut receiver is drilled and tapped, allowing shooters to mount a red dot or other optic directly without additional machining.

The 940 Pro JM wears Black Multicam synthetic furniture and an adjustable shim stock that lets you tune length of pull and comb drop to your exact fit. Gold oversized controls on the bolt handle, safety, bolt release, and loading gate give competition shooters fast, positive manipulation under pressure.

Up top, a HiViz CompSight fiber-optic sight rides on the vent rib for quick, intuitive target acquisition. The shotgun ships with a set of Briley extended chokes to dial in pattern density for 3-Gun stages, trap, or sporting clays.

At 7.75 lbs and 44.75" overall, this right-hand semi-auto balances naturally for swing-and-shoot competition while staying light enough to carry all day.
