The Mossberg 940 Pro Tactical SPX has perfected the brand’s self-regulating, semiautomatic gas system. Within the forend is a clean-operating vent arrangement that reduces the frequency for necessary maintenance when compared to previous 930 and 940 versions.
Seemingly every part was reconsidered and received enhancement. The optic-ready aluminum receiver supports direct mounting of refllex sights with an RMSc footprint. Mossberg also provides adapter plates for mounting optics with the RMR-, Docter- or DeltaPoint Pro-pattern interface. The receiver is also drilled and tapped to accept an optic rail, and users can default to using the provided low-profile fiber-optic front and rear ghost-ring sights for aiming.
Working the action of the 940 Pro Tactical SPX consists of manipulating the redesigned oversized tang safety switch, the large and knurled charging handle, and bolt release button. Everything was touched.
Organizing accessories such as lights and slings is easier with a fresh forend design that sports two quick-detach (QD) cups, three M-Lok mounting points, and tacky texture to every control point. Concealed underneath the forend are two integrated heat shields to protect the support hand.

Capacity of the magazine tube is either five or seven shells depending on model. Spare shells can be organized in the Vang Comp Systems 6-Shotshell Carrier, which is removable due to a hook-and-loop strip. This spare shell carrier is standard on all 940 Pro Tactical SPX models.
Configuring the 940 Pro Tactical SPX to comfortably fit a shooter’s shoulder is accomplished by customizing the stock spacer system. If you take the time to explore different spacers, its length of pull can be incrementally adjusted between 12 1/2 to 14 1/4 inches. Besides personalizing fit, the 940 Pro Tactical SPX is offered in Cerakote coatings and finishes to suit your style.
