A new durable gas system allows for up to 1500 rounds between cleaning. 

Offered as a “competition-ready shotgun”, the 940 JM Pro is built around a new durable gas system that allows for up to 1500 rounds between cleanings. Internal parts are nickel boron-coated for smooth operation, with competition-level loading port, elevator, and follower. 

Stock is user-adjustable for length of pull (13 – 14.25 inches) and for drop at comb and cast using incremental stock shims. Both forend and stock feature Mossberg’s signature texturing for a comfortable grip.

The 940 JM Pro has been designed in conjunction with world champion shooter Jerry Miculek.

In detail, the new gas system on the 940 will can reliably cycle any type of quality factory-made 2 3⁄4 or 3-inch ammunition. A stepped and vented-spacer component has also been incorporated that keeps the gas system running fast by shedding any moisture or carbon build-up every time it cycles. The 940’s loading port has been designed to allow the user to efficiently quad-load the magazine tube straight out of the box without any need of modification to the receiver, while the elevator and shell catch have also been designed to eliminate common pinch-points. The receiver is anodized for durability and the controls (charging handle and bolt release button) are oversized.

Receivers are anodized (in tungsten gray or black). Note the gold-anodized bolt handle and bolt release button. The enlarged and beveled loading port was specifically configured for quad-loading.

Mossberg engineers also worked to design  a new barrel-making process  for the 940 that will allow a user to maintain an accurate point-of-aim/point-of-impact when utilizing quality factory-made ammunition.

As for the sight system, the 940 JM Pro utilizes a fiber optic HIVIZ TriComp sight system that offers nine user-interchangeable LitePipes, in three colors and three shapes of varied height.
