The Mossberg 940 Pro Tactical SPX shotgun is a semi-automatic 12-gauge built for shooters who need speed, modularity, and reliability in a home-defense or tactical platform. This 18.5" barrel variant comes already mounted with a Holosun HS407k red dot, so you're ready to run optics right out of the box—a huge advantage if you're setting up a duty gun or home-defense shotgun without fumbling through mounting plates. The SPX nameplate signals this is the fully-loaded version of the 940 Pro Tactical line, and Mossberg hasn't cut corners.

The real story here is the forend. Mossberg integrated a heat shield into the rails-and-slots design, so you can mount lights, lasers, and other M-Lok accessories while keeping your support hand clear of a scorching barrel after rapid fire. The included Vang Comp 6-shot shell carrier lashes to the stock for fast reloads, and the adjustable-length-of-pull synthetic stock (ranging from 12.5" to 14.25") fits different frames and lets you dial in length-of-pull for your body and gear setup. QD ports on both the forend and stock mean your optics and flashlight mounting points are flexible. Add fiber-optic ghost ring irons as a backup, an oversized safety and bolt release for gloved operation, and a gas-vent system that keeps the gun running clean, and you're looking at a shotgun that takes itself seriously.

The 940 Pro Tactical SPX ships with the Holosun 407k already installed on the Shield RMSc footprint. If you ever want to swap optics, Mossberg includes three additional adapter plates so you can mount RMR, Docter, or Leupold footprint optics instead. The receiver is drilled and tapped, and the 3" chamber handles both 2¾" and 3" shells, giving you flexibility in ammo choice. With a 7-round magazine tube and clean handling, this is a shotgun that scales from sport shooting to serious work.
