Description
I remember the first time I shouldered a Winchester Super X3 Waterfowl Hunter 20 Ga 28″ Barrel 3″ Chamber Mossy Oak Shadow Grass Blades Finish 4rd. It was a cold, damp Missouri morning, the kind where your breath hangs in the air and the decoys bob silently on the water. I’d been through a few autoloaders that day, but the moment I picked up the SX3, the balance was just… different. It pointed like an extension of my arm, and the action cycled Winchester’s own Super-X loads without a hiccup. That’s the story this gun tells—it’s not just a tool, it’s a reliable partner built for the specific, demanding rhythm of waterfowling.
The Winchester Super X3 Waterfowl Hunter 20 Ga 28″ Barrel 3″ Chamber Mossy Oak Shadow Grass Blades Finish 4rd is a gas-operated semi-automatic shotgun purpose-built for waterfowl hunting. It features a 28-inch barrel, a 3-inch chamber, a Mossy Oak Shadow Grass Blades camo finish, and a 4-round capacity, designed for reliability, fast handling, and corrosion resistance in wet environments.
Let’s talk about what makes this gun stand out in the blind. The heart of the SX3 is its Active Valve gas system. It’s a self-regulating system that handles everything from light 2¾-inch target loads to the stoutest 3-inch magnum waterfowl shells. I’ve put everything from cheap promo loads to heavy Bismuth through mine, and it just runs. The system also does a fantastic job of reducing felt recoil, which you’ll appreciate after a long day of pass shooting. That smooth operation is a big part of why you’re looking at a price of $1064.45.
The Mossy Oak Shadow Grass Blades finish isn’t just for show. It’s a durable, dipped coating that covers the entire receiver, barrel, and fore-end, providing solid protection against moisture, mud, and the abrasive wear of a layout blind or boat. The 28-inch barrel gives you that longer sight plane for consistent swings on crossing birds, while the back-bored design and Invector-Plus choke system (it comes with a Modified choke) throw dense, even patterns. Weighing in at a nimble 6.8 pounds, it carries easily all day without feeling whippy or unstable.
One of the best features? It’s drop-in ready. You take it out of the box, give it a light lubrication, and it’s good to go. The Inflex Technology recoil pad is already doing its job, and the stock dimensions are spot-on for a clean mount. No gunsmithing required to get this into the field. It’s available at firearms-missouri.com for Missouri residents and nationwide, so getting one in your hands is straightforward.

Pros & Cons
Here’s the thing—no gun is perfect for everyone. The pros are significant: incredible reliability across a wide range of loads, reduced felt recoil, and a finish that truly holds up to the elements. The balance is fast and natural. The cons? Some hunters might find the 20-gauge a bit light for extreme-range geese, though modern non-toxic loads have closed that gap considerably. And while the camo is excellent, it’s a specific pattern best suited for certain environments.
Who This Is For
This is for the dedicated waterfowler who spends seasons in the marsh. It’s for the hunter who values a light, fast-handling gun that won’t quit when it’s coated in freezing mist. It’s also an excellent choice for a younger or smaller-framed shooter moving up from a youth model, thanks to that manageable 20-gauge recoil. If you chase ducks in flooded timber or layout boats for divers, this shotgun is built for your world.
Frequently Asked Questions
Q: Is the camo finish just on the outside, or does it cover internal parts too?
A: The Mossy Oak Shadow Grass Blades finish is a full coverage dip. It covers the entire exterior metal and synthetic surfaces, including the receiver inside and out, for maximum corrosion protection. The bolt and other internal working parts have their own protective finishes.
Q: What chokes does it use, and are others available?
A: It uses the Winchester Invector-Plus choke system. It comes with a Modified choke tube installed. You can purchase additional Invector-Plus tubes (like Improved Cylinder, Full, or specialized waterfowl chokes) from brands like Carlson’s or Briley to tailor your pattern for different situations.
Q: Can it handle steel shot?
A: Absolutely. The barrel is specifically designed and proofed for use with steel shot, as well as other non-toxic alternatives like Bismuth and Tungsten-based loads. Always use chokes rated for steel shot when using steel.
