This 940 JM Pro is set up for performance with a gas-operated, semi-automatic action and an extended tubular magazine running nearly to the muzzle for a 9+1 capacity. The 24-inch vent-rib barrel provides a clear sighting plane, anchored by a green fiber-optic bead for quick target acquisition.
The receiver is aluminum with a tungsten gray finish and is drilled and tapped, with three plug screws fitted. Oversized gold controls — charging handle, bolt release, trigger, and the ambidextrous tang safety — offer confident control and easy manipulation.
The Accu-Choke threaded muzzle adds flexibility, and this example includes Briley extended Modified and Cylinder choke tubes. The synthetic forend and black synthetic stock feature textured surfaces for a secure hold, and the stock includes a recoil pad with a 13.6-inch length of pull.
Built in the USA, this JM Pro configuration focuses on fast handling and durability, combining competition-oriented capacity with practical ergonomics. The overall package delivers a clean, straightforward setup ready for the range.
