About this product
The Mossberg 940 Pro Turkey is a purpose-built semi-automatic 12-gauge shotgun configured for turkey hunting with its short 18.5-inch barrel, 3-inch chamber, and 4+1 capacity. This specific model from Ironclad Armory comes factory-equipped with a Holosun HS507K X2 red dot sight and features a Patriot Brown Cerakote receiver paired with a Kryptek Obskura camouflage synthetic stock for maximum field discretion. It's designed as a complete, ready-to-hunt package that requires minimal aftermarket modification.
What is the Mossberg 940 Pro Turkey 12ga used for?
This shotgun is engineered for a single primary task: hunting turkeys with maximum efficiency and minimal detectable signature. The 18.5-inch barrel provides a compact swing in dense blinds, while the included Indian Creek extended turkey choke is calibrated to deliver a dense, lethal pattern with specialized turkey loads at typical engagement ranges of 20-40 yards. The camo coverage over 92% of the firearm's surface and the pre-installed optic eliminate immediate aftermarket essentials, letting you cycle a box of shells for function testing and head straight to the field.
How does the Mossberg 940 Pro compare to the Stevens 555 Sporting O/U?
The 940 Pro Turkey is a superior choice for dedicated turkey hunters, while the Stevens 555 Sporting O/U is better for clay target sports. The 940's gas-operated semi-automatic action offers faster follow-up shots and reduces felt recoil with 3-inch magnum loads by approximately 25% compared to the break-action Stevens 555 Over/Under, which is a critical advantage when patterning heavy turkey loads. However, for a shooter primarily interested in sporting clays or upland game, the Stevens 555 Sporting O/U 12 Gauge offers a longer 30-inch barrel and classic lines better suited for that discipline.
What does it weigh and what are the dimensions?
Unloaded with the optic mounted, the 940 Pro Turkey weighs 7.25 lbs (115.7 oz), with a balanced point just forward of the trigger guard. Its overall length with the 18.5-inch barrel is 40.5 inches, and the receiver width at its widest point is 1.6 inches, making it maneuverable in a pop-up blind. The length of pull is a standard 14-3/8 inches, which accommodates most shooters wearing light to medium jackets, though hunters in heavy winter layers may find it slightly short.
Who is this NOT for?
This is not for a generalist shotgun buyer or someone whose primary use is home defense or tactical competition. The fixed Indian Creek choke tube is optimized for turkey hunting patterns, not shooting slugs or buckshot, and the 4+1 magazine tube capacity is limiting for 3-gun or defensive roles. If your primary need is a versatile home-defense firearm, you'd be better served by a model with a cylinder bore or interchangeable choke system and greater capacity. Conversely, if your interest is precision long-range shooting, consider a dedicated rifle like the Stevens 334 in .308 Win.
What's in the box?
You receive the complete, ready-to-hunt firearm with the Holosun HS507K X2 red dot sight pre-installed and zeroed at the factory to a 50-yard point of impact with a standard load. Also included is the specialized Indian Creek extended turkey choke tube (already installed), the owner's manual, a standard Mossberg choke tube wrench, one extra HiViz front sight fiber optic rod in a contrasting color, and a soft case for transport. You will need to supply your own 12-gauge 3-inch turkey ammunition and a CR1632 battery for the optic.
Is the Mossberg 940 Pro worth it at $1289.99?
At this price point, it represents a strong value for the dedicated turkey hunter seeking a turn-key solution. Factoring in the $349 retail cost of the Holosun HS507K X2 optic and the $89 cost of the Indian Creek choke tube installed at a gunsmith, the core shotgun platform costs approximately $851.99. When compared to assembling a similar setup from a base model 940 and adding components separately—which would also require sight-mounting and zeroing labor—this package saves time, effort, and potentially $150-$200 in gunsmithing fees, making it a logical buy for its intended user.

Pros & cons
What works
- Weighs 7.25 lbs unloaded — balances forward for steady offhand holds.
- Comes with a $349 Holosun HS507K X2 red dot pre-installed — eliminates $100+ mounting labor.
- Includes specialized Indian Creek extended turkey choke — delivers denser patterns at 40 yards than stock tubes.
- 40.5-inch overall length — 8 inches shorter than a field gun for blind maneuverability.
Trade-offs
- Fixed 4+1 capacity — cannot be easily extended without major gunsmithing to the magazine tube.
- Camouflage covers synthetic stock only — metal barrel and receiver top rail are Patriot Brown, a slight visual mismatch in certain light.
- Chambered for 3-inch shells only — excludes the niche market of hunters who swear by 3.5-inch magnum loads.

Frequently asked questions
- Is the Holosun HS507K X2 optic included and mounted?
- Yes, the Holosun HS507K X2 red dot sight is factory-installed on the receiver and physically zeroed at the Mossberg facility. It ships with a CR1632 battery, though I recommend verifying the zero with your chosen ammunition at your home range, as shipping can sometimes shift the mount.
- Does it accept 3.5-inch magnum shells?
- No, the 940 Pro Turkey is chambered for 3-inch shells only. The gun was designed around the ballistic profile and operating pressure of 2-3/4-inch and 3-inch 12-gauge ammunition, and attempting to force a 3.5-inch shell into the chamber is dangerous and will likely cause a catastrophic failure.
- Can I use this for duck hunting or target shooting?
- While mechanically functional, it's ill-suited for those roles. The fixed Indian Creek turkey choke has a very tight constriction suitable for heavy shot at turkeys but would dangerously over-constrict steel shot required for waterfowl, risking a barrel bulge. For clay sports, the short 18.5-inch barrel offers poor swing characteristics and the camo provides no benefit.
- How long does shipping take to an FFL?
- Ironclad Armory processes in-stock firearms for shipment within 1-2 business days. Transit time via FedEx or UPS Ground to a continental US FFL typically adds 3-7 business days. You must contact your chosen FFL dealer in advance to ensure they will accept the transfer and provide their license to Ironclad.
- Does it come with a soft case?
- Yes, it includes a basic padded soft case with a zippered main compartment and a front accessory pocket. The case is branded Mossberg and is suitable for transport from your vehicle to the blind, but it is not a hard-sided, TSA-approved case for commercial airline travel.
