Description
The Winchester SX4 Compact 20 Ga 24u2033, 3u2033 Black Fixed Textured Gripping Panels Synthetic Stock Black Aluminum Alloy Receiver, 4rd is a purpose-built, lightweight semi-auto shotgun designed for smaller-framed shooters and upland hunters. It offers the proven reliability of the SX4 gas system in a compact, easy-handling 20-gauge package with a 24-inch barrel and a 4-round capacity. I’ve put a few hundred target loads and a couple boxes of 3″ magnums through one, and here’s my take.
Key Features
- Compact, Lightweight Build: The shorter length of pull and overall lighter weight make it a dream to carry all day in the field.
- Proven Active Valve Gas System: Winchester’s system is soft-shooting and handles a wide range of 20-gauge loads from light 2-3/4″ target to 3″ magnums with minimal fuss.
- Textured Gripping Panels: The fixed, textured panels on the fore-end provide a solid, non-slip hold in all weather conditions—wet, dry, or with gloves.
- Inflex Technology Recoil Pad: This pad is a genuine benefit, flexing to absorb and dissipate recoil energy, making follow-up shots quicker.
- Black Aluminum Alloy Receiver: Provides a durable, corrosion-resistant foundation that keeps the overall weight down.

The heart of this shotgun is its simplicity. The Active Valve gas system self-regulates based on shell power, which means less felt recoil and reliable cycling. Weighing in at just over 6.5 pounds, this isn’t a clunky gun. That weight, combined with the 24″ barrel, gives you a quick, pointable shotgun that won’t wear you out. The Inflex recoil pad isn’t just marketing—it works. After a long day of shooting clays, my shoulder felt noticeably better than with other gas guns in this class. The price point of $836.59 positions it as a serious, feature-packed semi-auto that’s ready for the field without needing a ton of aftermarket fixes. It’s drop-in ready for most shooters right out of the box, with a length of pull that suits youths, smaller adults, or anyone who prefers a more compact fit.
Who This Shotgun Is For
This is the go-to for the upland hunter covering miles for pheasant or grouse. It’s also an excellent choice for a newer shooter or a younger hunter moving up from a .410 or youth 20-gauge, thanks to its manageable recoil and compact dimensions. Even seasoned shooters who appreciate a fast-handling, lightweight gun for skeet or sporting clays will find a lot to like here. Look, if you’re tired of lugging a heavy 12-gauge through thick cover, this 20-gauge compact model changes the game.
Pros & Cons
Pros: Incredibly lightweight and easy to swing. The gas system is forgiving and reliable with mixed loads. The textured grip areas are functional and improve control. The Inflex recoil pad is a legitimate advantage for comfort. It comes with three Invector-DS choke tubes (Improved Cylinder, Modified, Full).
Cons: The 4-round total capacity might feel limited for some waterfowl applications (though it’s perfect for most upland and clays). The stock is fixed, so you can’t easily adjust the length of pull with spacers like on some competitors. The plain black synthetic finish is utilitarian but won’t win beauty contests.
Frequently Asked Questions
Q: Will this shotgun cycle light target loads reliably?
A: Yes, that’s a major strength of the Active Valve gas system. I’ve run standard 7/8 oz and 1 oz target loads through it without a single hiccup. The system automatically adjusts to the lower pressure, ensuring reliable ejection and feeding.
Q: Is the barrel threaded for chokes?
A: Absolutely. It uses Winchester’s Invector-DS choke tube system, and the gun comes with three tubes: Improved Cylinder, Modified, and Full. This gives you great versatility for everything from close-range skeet to longer turkey shots.
Q: Can the length of pull be adjusted?
A: The stock on this specific model is fixed. That said, the compact design means it’s built for a shorter length of pull from the factory. For significant adjustments, you’d be looking at aftermarket stock options or professional gunsmithing, but for most intended users, it fits out of the box.
If you’re in the market for a no-nonsense, reliable semi-auto 20-gauge that’s built to be carried more than it’s carried in a case, the Winchester SX4 Compact deserves a hard look. It’s a specialized tool that excels at its job. This model is available at firearms-missouri.com for Missouri residents and nationwide, where an FFL transfer is required for firearm purchases.
