Mossberg 935 Waterfowl 12ga Semi-Auto, 28in Barrel, 3.5in
About this product
The Mossberg 935 Waterfowl is a 12 gauge semi-automatic shotgun designed specifically for waterfowl hunting with its 28-inch overbored barrel and 3.5-inch chamber capability. Built with Mossy Oak Shadow Grass Blades camo synthetic stock and weighing 7.75 pounds, it handles both 3-inch and 3.5-inch magnum shells reliably. The Accu-Mag choke system and fiber optic front sight provide versatile patterning options for various waterfowl scenarios.
What is the Mossberg 935 Waterfowl used for?
The Mossberg 935 Waterfowl is designed specifically for waterfowl hunting where 3.5-inch magnum shells are required for maximum range and knockdown power. With its 28-inch overbored barrel reducing recoil by approximately 15% compared to standard barrels, the Accu-Mag choke system provides pattern flexibility from 20 to 50 yards. The Mossy Oak Shadow Grass Blades camo effectively breaks up your silhouette in marsh and field environments.
How does the Mossberg 935 Waterfowl compare to the Stevens 555 Sporting O/U?
The Mossberg 935 outperforms the Stevens 555 Sporting O/U in waterfowl applications due to its 3.5-inch chamber capability and higher 4+1 capacity versus the Stevens' 2-round capacity. While the Stevens offers quicker second-shot capability with its over/under design, the Mossberg's semi-auto action handles heavy magnum loads more comfortably with reduced felt recoil. For dedicated waterfowl hunting where shell capacity and magnum performance matter, the Mossberg is the superior choice.
What does it weigh and what are the dimensions?
The Mossberg 935 Waterfowl weighs 7.75 pounds with an overall length of 49.5 inches due to its 28-inch barrel. The length of pull measures exactly 14 inches with a synthetic stock that provides consistent cheek weld and shoulder placement. At 7.75 pounds, it's heavy enough to absorb recoil effectively but light enough for extended carries through marsh terrain.
Who is this NOT for?
This shotgun is not suitable for left-handed shooters due to its right-hand-only ejection pattern and safety placement. The 7.75-pound weight and 49.5-inch length also make it cumbersome for smaller-framed hunters or those requiring compact firearms for tight blind spaces. If you primarily hunt upland game or need ambidextrous controls, consider the Stevens 555 Sporting Compact instead.
What's in the box?
The package includes three Accu-Mag chokes: Full, Improved Cylinder, and Modified patterns for different shooting distances. You'll also receive a 4-round magazine tube, owner's manual, and warranty documentation. The fiber optic front sight comes pre-installed and zeroed at the factory for immediate field use.
Is the Mossberg 935 Waterfowl worth it at $790.99?
At $790.99, the Mossberg 935 Waterfowl offers excellent value for serious waterfowl hunters needing 3.5-inch capability. Compared to competing semi-autos in this category that often exceed $1,000, you're getting proven reliability with Mossberg's gas system and corrosion-resistant finishes. The included $120 worth of Accu-Mag chokes and camo pattern make this a complete waterfowl package without additional accessories.

Frequently asked questions
- Is it compatible with aftermarket chokes?
- Yes, it uses Mossberg's Accu-Mag choke system which accepts any Accu-Mag compatible tubes. The threads are standard and will not work with Benelli Mobilechoke or Browning Invector systems. You must use Mossberg-specific Accu-Mag chokes for proper patterning.
- Does it fit in a standard 52-inch gun case?
- Yes, the 49.5-inch overall length fits comfortably in standard 52-inch cases with room for accessories. I recommend Plano All-Weather cases for maximum protection during transport to hunting locations. Allow 2-3 inches clearance for scope or sight protectors if added.
- How long does shipping take?
- Standard shipping takes 3-5 business days for in-stock items through FedEx Firearms Program. All firearms ship to your local FFL dealer who will conduct the required background check, which typically adds 1-2 business days for processing. Express shipping is available for an additional $35 fee.
- Can I return it if it doesn't fit?
- Firearms purchases are final unless defective, per ATF regulations and Ironclad Armory policy. We recommend handling similar models at local dealers before purchasing. If the firearm arrives damaged or malfunctions, we cover return shipping and provide replacement within 14 business days through our warranty program.
- Does this work with standard 2.75-inch target loads?
- Yes, it cycles 2.75-inch target loads reliably after proper break-in with 50 rounds of 3-inch magnum loads. The gas system requires high-pressure shells to function optimally—use loads rated at 1,200 fps or higher for consistent cycling. Light target loads below 1⅛ oz may experience occasional cycling issues.
