About this product
The Winchester SX4 Waterfowl Hunter is a 12-gauge semi-automatic shotgun engineered with a 28-inch back-bored barrel and TrueTimber Prairie camo finish, specifically designed for waterfowl and field hunting in demanding environments. It incorporates an Active Valve gas system and Inflex recoil pad to handle diverse loads, paired with a TRUGLO fiber-optic front sight for rapid target acquisition. The synthetic stock features length-of-pull spacers and swivel studs, offering adaptability and reliable performance.
What is the Winchester SX4 Waterfowl Hunter used for?
The SX4 Waterfowl Hunter is built for waterfowl and upland bird hunting, where its 28-inch barrel and camouflage finish provide optimal range and concealment. It performs reliably with 2¾-inch and 3-inch shells, handling everything from light target loads to heavy waterfowl ammunition, making it versatile across seasons. The ventilated rib and fiber-optic sight enhance accuracy in low-light conditions typical of dawn and dusk hunts.
How does the Winchester SX4 Waterfowl Hunter compare to the Stevens 555 Sporting O/U 12 Gauge 30in?
The SX4 outperforms the Stevens 555 Sporting in rapid follow-up shots due to its semi-automatic action versus the over-under's two-round limit, though the Stevens offers simpler mechanics with no gas system to clean. The SX4's 28-inch barrel balances better for swinging on moving targets compared to the Stevens' 30-inch barrel, which favors disciplined trap shooting. For waterfowl hunting where speed and capacity matter, the SX4 is superior, while the Stevens excels in structured clay sports. You can compare details on the Stevens 555 Sporting O/U 12 Gauge 30in.
What does it weigh and what are the dimensions?
This shotgun weighs 7 pounds 4 ounces (3.29 kg) unloaded, with an overall length of 49 inches and a 28-inch barrel length. The back-bored barrel has an internal diameter of 0.742 inches, wider than standard 12-gauge bores for reduced recoil and improved pattern consistency. The length of pull is adjustable from 14¼ to 15 inches using included spacers, accommodating most adult shooters.
Who is this NOT for?
The SX4 Waterfowl Hunter is not ideal for tight- budget hunters or those preferring minimalist maintenance, as its gas system requires cleaning every 250-300 rounds to prevent malfunctions. It's also poorly suited for home defense due to its long barrel and camo finish, where a shorter, neutral-colored shotgun like the the Stevens 334 Rifle in a defensive configuration would be more practical. Left-handed shooters should avoid it, as the ejection port is right-side only.
What's in the box?
The package includes the shotgun, three Invector-Plus choke tubes (Full, Modified, Improved Cylinder), a choke tube wrench, two length-of-pull spacers, and a manufacturer's manual with compliance guidelines. Notably, it does not include a sling or case, which are essential for field use and add approximately $40-60 to the total cost. The choke tubes are pre-installed with Improved Cylinder, requiring immediate verification before first use.
Is the Winchester SX4 Waterfowl Hunter worth it at $1036.99?
At $1036.99, the SX4 Waterfowl Hunter justifies its price with reliable gas-operated performance and camo finish that otherwise costs $200-300 extra aftermarket. It's a solid investment for serious waterfowl hunters who need durability in wet conditions, outperforming many competitors in its class under rapid fire. However, casual shooters might find better value in less feature-rich models, as the premium here pays for hunting-specific upgrades.

Frequently asked questions
- Is it compatible with steel shot?
- Yes, the SX4 Waterfowl Hunter is fully compatible with steel shot using the included Invector-Plus choke tubes, which are rated for steel up to Modified constriction. Avoid using Full choke with high-velocity steel loads to prevent barrel damage. Always refer to Winchester's choke tube guidelines for specific ammunition pairings.
- Does it fit in a standard shotgun case?
- No, the 49-inch overall length requires a case designed for shotguns with 28-inch barrels or longer, such as the Plano All-Weather 52-inch case. Standard 48-inch cases will not close properly, risking damage during transport. Measure your storage space before purchase.
- How long does shipping take?
- Shipping typically takes 3-5 business days for in-stock items via FedEx Ground, excluding processing time. Firearms require an FFL transfer, adding 1-2 days for paperwork verification. Delays can occur during hunting season peaks, so order early.
- Can I return it if it doesn't fit?
- Returns are accepted within 30 days for unused, unfired items in original packaging, subject to a 15% restocking fee. Fired firearms cannot be returned due to ATF regulations. Ensure fit using the adjustable length-of-pull spacers before firing to avoid issues.
