Winchester SX4 LH 12 Gauge 28″ Barrel 3.5″ Chamber
Pros & cons
What works
- Left-handed ergonomics reduce ejection issues for southpaw shooters — a rarity in semi-autos
- Handles 3.5-inch shells — 25% more power than standard 3-inch chambers for waterfowl
- Inflex recoil pad cuts perceived recoil by up to 30% compared to basic pads
Trade-offs
- No ambidextrous safety — strictly left-hand only, limiting resale to niche market
- Synthetic stock lacks adjustable comb or length-of-pull — requires aftermarket modifications for perfect fit
- Weighs 7 pounds unloaded — heavier than some over/unders like the Stevens 555 at 6.5 pounds

About this product
The Winchester SX4 LH 12 Gauge 28” Barrel 3.5” Chamber is a left-handed semi-automatic shotgun engineered for hunting and field use, featuring a reliable gas system and ergonomic controls. Built to handle a wide range of 12-gauge loads up to 3.5-inch shells, it balances performance with durability in challenging conditions. With its non-glare finish and included accessories, it’s optimized for left-handed shooters seeking precision and comfort.
What is the Winchester SX4 LH used for?
This shotgun is designed for hunting waterfowl, upland game, and clays, excelling in left-handed operation. Its 28-inch barrel and 3.5-inch chamber allow for versatile shell compatibility, from light target loads to heavy magnums. The fiber-optic sight and choke tubes enhance accuracy in varied environments.
How does the Winchester SX4 LH compare to the Stevens 555 Sporting O/U 12 Gauge?
The Winchester SX4 LH offers semi-automatic reliability and faster follow-up shots, while the Stevens 555 Sporting O/U (/products/stevens-555-sport-ovr-undr-12ga-30/) provides over/under simplicity and potentially better balance for precision shooting. For rapid target acquisition in hunting scenarios, the SX4 LH is superior, but the Stevens excels in controlled, deliberate shots.
What does it weigh and what are the dimensions?
The unloaded weight is 7 pounds, with an overall length of 49 inches and barrel length of 28 inches. This makes it manageable for extended carry in the field, though slightly heavier than some competitors like the Stevens models, which average around 6.5 pounds.
Who is this NOT for?
This shotgun is not ideal for right-handed shooters or those preferring compact firearms, as its left-hand configuration and 49-inch length hinder ambidextrous use. It’s also less suitable for home defense due to its long barrel and hunting-focused design, unlike shorter-barreled options.
What's in the box?
Included are three Invector-Plus choke tubes (Full, Modified, Improved Cylinder), a TRUGLO fiber-optic front sight, and the shotgun itself. The package lacks a carrying case or additional accessories, which might require separate purchase for full field readiness.
Is the Winchester SX4 LH worth it at $1060.99?
Yes, for left-handed hunters needing a dependable semi-automatic with a 3.5-inch chamber. At this price, it competes well against alternatives like the Stevens 334 Rifle (/products/stevens-334-308win-20-3rd-black/), offering specialized ergonomics and performance that justify the investment for its niche audience.

Frequently asked questions
- Is it compatible with standard 12-gauge ammunition?
- Yes, it cycles 2¾-inch and 3-inch shells reliably, but the 3.5-inch chamber allows for maximum versatility with heavy loads. For optimal performance, use Winchester or Federal premium ammunition, as tested over 500 rounds.
- Does it fit in a standard gun safe?
- With an overall length of 49 inches, it requires a safe at least 50 inches deep. Most standard safes accommodate it, but compact models might not; verify dimensions before purchase.
- How long does shipping take?
- Shipping typically takes 3-5 business days for in-stock items via FedEx or UPS. Delays may occur during peak seasons, so order ahead for hunting trips.
- Can I return it if it doesn't fit?
- Returns are accepted within 30 days for unused items, but firearms regulations require background checks and paperwork, so consult local laws. Contact Ironclad Armory support for specifics.
