Description
The 940 PRO TACTICAL – HOLOSUN MICRO DOT COMBO is a purpose-built, semi-automatic tactical shotgun system.

This combo ships to Missouri and compliant US states, arriving drop-in ready for immediate use.
Key Features

Weighing in at approximately 7.5 pounds unloaded, the 940 Pro Tactical balances heft for recoil management with agility for dynamic handling. The total package price of $1015.19 represents a significant value versus purchasing the shotgun and optic separately. When it comes to home defense, having a sighting system you can trust under stress is non-negotiable—this combo delivers that confidence from the first round. The system is also compatible with a wide range of aftermarket accessories designed for Mossberg shotguns, including M-LOK forends from brands like Magpul.
Who This Combo Is For
This package is for the shooter who needs a dependable, no-fuss defensive tool that works the first time and every time. It’s ideal for the homeowner seeking a serious advantage in a critical incident, the tactical shotgunner wanting a modernized autoloader, or the prepper valuing a robust, optics-ready platform. It bypasses the guesswork of selecting and mounting a dot, providing a proven, zeroed solution.
Pros & Cons
Pros: The primary advantage is its turnkey nature; the optic is mounted, aligned, and ready to go, saving time and potential gunsmithing fees. The gas system softens recoil noticeably compared to many inertia-driven shotguns, aiding faster follow-up shots. The ghost ring sights provide a reliable backup if the dot fails. Here’s the thing—the value is clear when you consider the combined cost.
Cons: As a dedicated tactical tool, it’s less suited for hunting or clay sports where longer barrels are preferred. The semi-auto action, while reliable, requires more detailed cleaning than a pump-action after extensive use. Some users may prefer a different reticle style, though the 2 MOA dot is an excellent all-around choice.
Frequently Asked Questions
Q: Is the Holosun sight already zeroed?
A: The sight is mounted at the factory, but final zeroing should always be confirmed by the end user with their chosen ammunition. The process is straightforward using the included tool and the iron sights as a reference point.
Q: What type of battery does the Holosun HS407K use?
A: It uses a common CR1632 battery, which provides up to 50,000 hours of runtime. The Shake Awake feature conserves power by activating the dot upon movement.
Q: Can I add a light or sling to this shotgun?
A: Absolutely. The synthetic forend has integrated M-LOK slots for attaching weapon lights like a Streamlight TLR-1 or pressure pads. The stock includes a swivel stud, and the receiver has a rear sling point, making sling attachment simple.
