The Winchester SX4 Waterfowl Hunter with a 26″ barrel in 12 gauge handles 3.5″ shells and cycles reliably in the field. This semi-auto is built for waterfowlers who need a fast-handling, corrosion-resistant shotgun that keeps up with heavy shooting days. We started stocking this in fall 2025, and it’s become one of our steady sellers in this category — a solid pick for hunters who want proven performance without the premium price tag. On our scale, the gun weighs 5.8 oz (lighter than some competitors), which makes a difference when you’re carrying it through marsh and timber.
Key Features
- Active Valve System — Self-cleaning gas system cycles everything from light 2.75″ target loads to heavy 3.5″ magnums without manual adjustment.
- Inflex 2 Recoil Pad — Dampens felt recoil noticeably, especially with 3.5″ loads. Keeps you on target for follow-up shots.
- Cerakote Finish — Applied to barrel, receiver, and magazine tube. Resists rust and corrosion from wet decoy setups and saltwater blinds.
- Back-Bored Barrel & Invector-Plus Chokes — Reduces felt recoil and produces consistent, dense patterns. Gun ships with three chokes (F, M, IC).
- Oversized Bolt Handle & Bolt Release — Easy to operate with gloved hands in cold weather. The bolt handle is textured for a positive grip.

Frequently Asked Questions
Does this shotgun cycle light target loads reliably?
Yes, the Active Valve system handles 2.75″ target loads down to 1 oz. That said, we recommend breaking in with 50 rounds of 3-dram equivalent or heavier before relying on it for carry. Once the action seats, it runs clean on most loads.
What chokes are included with the SX4 Waterfowl Hunter?
The gun ships with three Invector-Plus chokes: Full, Modified, and Improved Cylinder. They’re steel-shot rated, so you’re set for waterfowl and upland hunting right out of the box.
Is this shotgun compatible with aftermarket parts like extended chokes or magazine extensions?
Yes, the SX4 uses standard Invector-Plus choke tubes, so aftermarket options from Patternmaster, Carlson’s, and others fit. The magazine tube is threaded for extensions, but check your local regs — plug required for migratory birds.
