Mossberg 940 Pro Tactical Holosun Combo Shotgun Review

The 940 Pro Tactical Holosun Combo Shotgun from Mossberg comes optic-ready, with receiver cuts that accept low-profile direct mounting of Shield RMSc-pattern micro dot sights for improved eye alignment and target acquisition. Inside, 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, and sear), plus an enlarged/beveled loading port, elongated elevator, and anodized follower for smooth operation. Outside, the adjustable stock allows for 1.75″ of LOP flexibility, the stock and streamlined forend feature Mossberg signature texturing for a secure grip, a barrel clamp provides accessory flexibility via M-LOK mounting slots, and a fiber optic front sight. Altogether, these features and more are what make the 940 Pro Tactical attractive on paper but how does she run on the range? We sent IV8888 out to the range to find out! This 940 is a sweet shotgun – you know we love the Mossberg 930 so we brought that along to do a little comparison of the two. They’re both gas-operated and relatively similar but they do have quite a few differences, which we’ll unpack today. My first exposure to the 940 was Jerry Micheluk’s personal gun he brought down to shoot with us which was actually a prototype when Mossberg originally started the 940 JM line of shotguns. The Pro version has a lot of the refinements that Jerry has on his competition shotgun which is basically a selling point in and of itself. Additionally, the 940 Pro Tactical has a nice nerling on the charging handle, a large tactical latch on the bolt release, a slimmer forend, and it’s definitely lightweight – it’s an extremely lightweight shotgun. Obviously, this model comes with a Holosun micro red dot mounted but the newer 940’s as well as the 590S are cut for optics mount. However, you can still mount a traditional rail on top if that’s what you prefer, the patterns for the holes are the same, you’ll just have the plate underneath, which is no big deal. You do have a barrel clamp at the end that gives you a couple of M-LOK accessories slots on this gun, a fiber-optic sight on the front, and the 940 is threaded for different chokes. I do really like the low profile of the red dot on this particular shotgun, it’s pretty cool.
