Description
The Winchester SX4 12 Gauge 26″ 3.5″ Black Synthetic is a field-proven semi-automatic shotgun built for the man who spends more Saturdays in the timber than in the truck. Chambered for 3½-inch shells, it cycles everything from light target loads to heavy magnum waterfowl rounds without a hiccup. The 26-inch barrel with a ventilated rib and TruGlo fiber-optic front sight gives you a fast, clear sight picture whether you’re swinging on a dove or picking a drake out of a decoy spread. This is the same reliable gas-operated action that has made the SX4 a favorite among Southern bird hunters, but now with a durable synthetic stock that shrugs off rain, mud, and morning dew.

Key Features
- Gas-operated semi-auto action – WHY IT MATTERS: Soaks up recoil from 3½” magnums, letting you stay on target for a fast follow-up shot on a flushing rooster or a crossing goose.
- Invector-Plus flush choke system – WHY IT MATTERS: Comes with multiple choke tubes so you can dial in your pattern for doves, ducks, or turkeys without buying extra hardware.
- TruGlo fiber-optic front sight – WHY IT MATTERS: Picks up light in low dawn or dusk conditions, giving you a bright aiming point when the birds are moving.
- 26-inch matte barrel with ventilated rib – WHY IT MATTERS: Reduces glare and heat mirage, keeping your sight picture clean during long shooting sessions in the field.
- 3½-inch chamber – WHY IT MATTERS: Lets you shoot the heaviest waterfowl loads when you need that extra reach on late-season geese.
Who It’s For
This Winchester SX4 is built for the Southern shooter who hunts everything from doves in September to ducks in January. It’s for the man who wants one shotgun that can handle a box of 2¾” target loads at the clays range and then digest a handful of 3½” steel shot without a burp. If you’re a bird hunter who values reliability over flash, this gun fits you like a good pair of boots.
Pros and Cons
- Pro: Cycles a wide range of loads reliably, from light target to heavy magnum.
- Pro: Lightweight enough to carry all day on a dove hunt.
- Con: The synthetic stock can feel a bit utilitarian compared to wood; some shooters prefer a more traditional look.

FAQ
Does this shotgun come with choke tubes?
Yes, the Winchester SX4 includes a set of Invector-Plus flush choke tubes (typically Full, Modified, and Improved Cylinder) so you can switch patterns based on your game. Per Winchester specs, the choke tubes are flush-mounted and do not extend past the muzzle.
Is this model suitable for left-handed shooters?
The SX4 is a right-handed design with the bolt handle and ejection port on the right side. Left-handed shooters can still use it, but you’ll need to be mindful of ejected shells crossing your line of sight. Winchester does not currently offer a left-handed version of this model.
What is the maximum shell length this gun can handle?
This shotgun has a 3½-inch chamber, meaning it can safely fire 2¾-inch, 3-inch, and 3½-inch shells. It’s a true magnum-capable field gun for waterfowl, turkey, and deer slugs.
How do I clean the gas system on the SX4?
Field-stripping is straightforward: remove the barrel, then pull the forend and gas piston assembly. Wipe carbon deposits from the piston and magazine tube with a solvent-soaked cloth. Relubricate lightly with gun oil before reassembly.
