Key Features
Left-hand controls — Why it matters: The safety, bolt release, and bolt handle are mirrored for lefties, so you don’t have to break your grip to operate them.
Back-bored 28″ vent rib barrel — Why it matters: Reduces recoil and produces denser, more consistent patterns compared to standard bores.
Invector-Plus choke system — Why it matters: Included flush chokes (F, M, IC) let you match the pattern to the bird or range without tools.
TruGlo fiber-optic front sight — Why it matters: High-visibility dot picks up ambient light, so you acquire the target fast in low-light dawn or dusk conditions.
Active Valve gas system — Why it matters: Self-regulates to cycle light target loads and heavy magnum waterfowl loads without adjustment.
Who It’s For
This is for left-handed hunters who want a dedicated gun, not a converted right-hander. Whether you’re chasing pheasants over pointing dogs or setting decoys for ducks, the SX4 Field LH gives you a natural fit that speeds up your second shot. It also suits left-handed shooters who shoot sporting clays or skeet and want a gas-operated gun that runs clean.
Pros & Cons
Pros: True left-hand controls, back-bored barrel reduces felt recoil, TruGlo sight is bright in any light, Invector-Plus chokes offer wide pattern flexibility, reliable cycling with everything from target loads to 3″ magnums.
Cons: The walnut stock lacks a shim system for drop/cast adjustment, so you’ll need to fit it as-is or have a stock fitted. Also, the receiver is not drilled and tapped for a rail, limiting optic mounting options to clamp-on saddle mounts.

The SX4 Field LH undercuts both the Benelli M2 and Beretta A400 by at least $280 while offering a similar gas system and left-hand ergonomics. The Benelli is lighter but has more felt recoil due to its inertia action. The Beretta has a Kick-Off recoil reducer but costs $530 more.
FAQ
Is the Winchester SX4 Field LH reliable with light target loads?
Yes. The Active Valve gas system regulates pressure to cycle everything from 1-oz target loads to 3″ steel waterfowl loads. It is one of the most reliable gas guns Winchester has made, with a 15% lower cyclic rate than the previous SX3, reducing felt recoil further.
Does the SX4 Field LH come with a shim kit for cast and drop adjustment?
No, it does not. The stock is fixed with a standard drop and cast. If you need custom fit, you’ll need to have a stock fitted by a gunsmith. This is a common omission at this price point.
Can I mount a red dot or scope on this shotgun?
The receiver is not drilled and tapped for a rail. You can use a saddle mount that clamps around the receiver, but it will add bulk. For most field use, the TruGlo fiber-optic front sight is sufficient.
Is this shotgun suitable for waterfowl hunting with steel shot?
Absolutely. The back-bored barrel and Invector-Plus chokes are steel-shot rated. Use the Improved Cylinder or Modified chokes for steel, and the Full choke for lead or bismuth.
