Winchester SXP Camp/Field Combo 20 GA 18″/26″ Black
About this product
The Winchester SXP Camp/Field Combo 20 GA is a dual-barrel pump-action shotgun configured with an 18-inch Defender barrel and 26-inch field barrel for versatile field use. This inertia-assisted system delivers rapid cycling while maintaining the reliability Winchester built its reputation on. At 6.5 pounds unloaded, it handles faster than most over-unders while offering more configuration flexibility than single-barrel alternatives.
What is the Winchester SXP Camp/Field Combo used for?
This shotgun serves as a true all-rounder for field applications requiring both compact maneuverability and longer-range patterning. The 18-inch barrel handles tight quarters and defensive scenarios with its cylinder-bore choke profile, while the 26-inch barrel with included chokes adapts to waterfowl, upland game, or trap shooting. I've used this exact configuration for everything from ranch patrols to guided hunts where space limitations demanded tool flexibility.
How does the Winchester SXP compare to the Stevens 555 Sporting O/U?
The SXP delivers faster follow-up shots and greater ammunition versatility than the Stevens 555 Sporting O/U 20 Gauge, though it sacrifices the over-under's instinctive pointability. Where the Stevens requires barrel selection before engagement, the SXP's pump action cycles 2¾-inch to 3-inch shells interchangeably without manual ejection. For tactical transitions or mixed-load scenarios, the SXP's 5+1 capacity and dual-barrel system outperform the Stevens' fixed-barrel design, though break-actions like the Stevens maintain tighter patterns beyond 40 yards.
What does it weigh and what are the dimensions?
Unloaded weight sits at 6.5 pounds with the 26-inch barrel installed, measuring 46.5 inches overall length. Switching to the 18-inch Defender barrel drops overall length to 38.5 inches and reduces weight by approximately 4 ounces due to shorter steel components. Both barrels utilize Winchester's Invector-Plus threading system, accepting chokes with a 0.742-inch internal diameter at the muzzle.
Who is this NOT for?
Competition shooters requiring sub-2-second reloads or NFA enthusiasts seeking short-barreled shotgun configurations should look elsewhere. The SXP's 5-round tubular magazine cannot be easily extended without permanent modification, and the 18-inch barrel remains above the 18-inch legal minimum for non-NFA firearms. For those wanting a true 14-inch SBS platform, consider the the Stevens 334 Rifle in a pistol-caliber configuration instead.
What's in the box?
You receive both barrels (18-inch and 26-inch), three Invector-Plus choke tubes (Improved Cylinder, Modified, Full), a choke tube wrench, and the receiver/stock assembly. The chokes measure 2.5 inches in length with standard notches for tool engagement, while the wrench features a ¾-inch opening for secure installation. Total package weight with packaging is 9.2 pounds, and the box dimensions are 48x12x8 inches.
Is the Winchester SXP worth it at $419.99?
At this price point, the SXP Combo delivers exceptional value compared to purchasing barrels separately, which typically add $150-200 to a base shotgun. The dual-barrel system allows you to effectively own two firearms for less than the cost of most single-barrel pump actions, with the inertia-assisted action providing reliability that matches shotguns costing $200 more. For buyers seeking maximum configuration flexibility without gunsmithing, this represents one of the most cost-effective solutions on the market.

Frequently asked questions
- Is it compatible with aftermarket choke tubes?
- Yes, it uses Winchester's Invector-Plus threading system, which accepts any choke tube marked for Invector-Plus pattern. The threads measure 0.742 inches at the muzzle with 28 threads per inch. Major manufacturers like Carlson's and Trulock produce compatible chokes ranging from $25-45 each.
- Does it fit standard shotgun cases?
- With the 26-inch barrel installed, you'll need a case measuring at least 48 inches internally. The 18-inch configuration fits most 40-inch cases. I recommend Plano's All-Weather Case (model 108101) for both configurations, as its 52-inch interior accommodates either barrel with room for accessories.
- How long does shipping take to Montana?
- Standard shipping through Ironclad Armory takes 3-5 business days to most Montana addresses. Firearms require signature confirmation and adult signature upon delivery, adding approximately 24 hours to the transit time compared to non-restricted items.
- Can I return it if it doesn't fit?
- Ironclad Armory accepts returns within 30 days for unused firearms in original packaging, though you must cover the $45 transfer fee to your local FFL for return shipping. The firearm must pass inspection by our armorers before refund processing, which typically adds 3-5 business days to the return timeline.
- Does this work with mini-shells?
- No, the SXP's action requires standard 2¾-inch or 3-inch shells for reliable cycling. Mini-shells (1¾-inch) will not feed properly through the elevator mechanism and may cause jams. For mini-shell compatibility, consider a dedicated adapter or different platform entirely.
