Inside the 940 autoloading shotguns, you'll find a durable gas system that allows for up to 1500 rounds between cleanings and a host of corrosion-resistant internal parts/finishing (nickel boron-coated gas piston, magazine tube, hammer/sear), enlarged/beveled loading port, elongated elevator, and anodized follower for smooth operation. Outside, an adjustable stock allows for 1.25a ^2 of LOP flexibility, the stock and streamlined forend feature Mossberg signature texturing for a secure grip, and a front fiber optic sight helps keep you on target.
