Key Features

- Durable Camo Finish: Full Mossy Oak camouflage coverage protects the metal and synthetic stock from the elements and helps you blend into your surroundings.
- Fast Handling: The 26-inch barrel length provides a smooth swing for fast target acquisition on flushing birds, making it a versatile choice for both ducks and pheasants.
- Inflex Technology Recoil Pad: Reduces felt recoil by flexing to absorb energy, which is a major plus during long days at the range or in the blind.

The SX4’s weight of approximately 6.8 pounds strikes a practical balance. It’s light enough to carry all day without becoming a burden, yet has enough mass to help soak up recoil and maintain a smooth swing. The 26-inch barrel is a popular and versatile choice, offering a good compromise between the ultra-quick handling of a 24-inch and the longer sight plane of a 28-inch barrel. This model uses the proven Invector-Plus choke system, which is shared with many Browning shotguns, giving you a wide range of affordable aftermarket choke options from brands like Carlson’s and Trulock.
Who This Shotgun Is For
This is a shotgun for the budget-conscious hunter who refuses to compromise on reliability. It’s built for the Missouri waterfowler who needs a gun that will cycle in cold, muddy conditions, or the upland hunter covering miles for pheasant and quail. If you’re stepping up from a pump-action or an older, less reliable autoloader, the SX4 offers a significant upgrade in smoothness and speed. It’s also a solid choice for a dedicated clay target gun for sporting clays or trap, especially given its ability to run light target loads without a hitch. The value proposition is clear: you get performance that rivals shotguns costing several hundred dollars more.
Pros & Cons: The Practical Tradeoffs
Pros: The primary advantage is cost. You get Winchester’s proven reliability and a feature set that includes a self-cleaning piston and a great recoil pad for hundreds less than a Beretta A300 or a Benelli. The gas operation is noticeably softer-shooting than many inertia-driven systems, which is a real benefit during long practice sessions. The Mossy Oak finish is durable and maintenance-friendly—just wipe it down. Finally, its compatibility with a huge array of Invector-Plus chokes means you can fine-tune your pattern without breaking the bank.
Cons: As a value-focused gun, some fit and finish details aren’t as refined as on more expensive European models. The stock is a one-size-fits-most proposition; if you need a significant length of pull adjustment, you’ll need to add spacers. While the camo is tough, the synthetic stock material can feel a bit more utilitarian compared to higher-grade polymers. That said, these are the exact tradeoffs that keep the price at a practical $819.86 and make it such a compelling ‘bang-for-buck’ option.
Frequently Asked Questions
Q: Will this shotgun reliably cycle light 2¾-inch target loads?
A: Yes, absolutely. The Active Valve gas system is designed to self-regulate, making it highly reliable with lighter target loads (often as light as 1 oz, 1180 fps) all the way up to 3-inch magnum waterfowl loads. This versatility is a key part of its value.
Q: What is the magazine capacity?
A: The plug installed for migratory bird hunting limits the capacity to 2+1 (two in the magazine, one in the chamber). With the plug removed, the total capacity is 4+1. Always check and comply with local hunting regulations for capacity limits.
Q: Is the camo pattern specific, and what choke tubes are included?
A: This model features a standard Mossy Oak Bottomland pattern, excellent for timber and many marsh environments. It comes from the factory with three Invector-Plus choke tubes: Improved Cylinder (IC), Modified (M), and Full (F), covering most hunting and clay shooting scenarios.
