    Built on Mossberg’s proven gas system, the 940 Pro Tactical SPX uses a nickel-boron coated gas piston, magazine tube, hammer, and sear to enhance corrosion resistance and simplify cleanup. The action is tuned for reliability, and an enlarged loading port works with the extended bolt release and oversized, knurled charging handle for confident control.

    The 18.5 inch steel barrel carries a matte blued finish and uses the Accu-Choke system with a Cylinder (CYL) bore, offering a straightforward, choke-compatible setup. Chambering accepts 2 3/4 or 3 inch shells. Capacity is an extended 7+1 with 2 3/4 inch shells or 6+1 with 3 inch shells, and the magazine tube runs to the muzzle.

    Target acquisition is fast and precise with metal ghost-ring sights and a protected fiber-optic front. The receiver is optic-ready from the factory, featuring a dedicated optic cut and a cover plate when no optic is installed.

    The aluminum receiver wears a hard-coat anodized black finish, while the synthetic stock and polymer forend deliver durability and positive handling. Stock features include an adjustable length of pull via spacers, a ventilated recoil pad, textured grip panels, a rear QD sling cup. The polymer forend integrates heat-shield styling and M-LOK slots at 3, 6, and 9 o’clock for accessory mounting. Tang safety placement keeps controls intuitive. Receiver markings observed include “940 PRO” and “MOSSBERG 940 12GA / NORTH HAVEN, CT USA.”
