About this product
The Weatherby Sorix Slough 20 Gauge 28" Semi-Auto is a full-size, inertia-driven semi-automatic shotgun built for waterfowl and upland hunters who demand unfailing reliability in adverse conditions. It represents Weatherby's direct application of the proven Benelli inertial system to a dedicated hunting platform, wrapped in durable, functional Slough camouflage. For the shooter who understands that reliable shell ejection in cold, muddy marshes is more critical than magazine capacity, this is a purpose-built tool.
What is the Weatherby Sorix Slough 20 Gauge used for?
This shotgun is engineered for waterfowl and upland bird hunting over decoys. The 28-inch barrel with a Benelli Crio Plus choke system generates consistent, dense patterns for ducks and geese at 30-40 yards, while the 6.5-pound weight allows for manageable carry and swift mounting in a blind. Its inertia-driven action is purpose-built to cycle light 7/8-ounce target loads through heavier 3-inch magnums without adjustment, making it ideal for hunters who transition between species in a single day.
How does the Weatherby Sorix Slough compare to the Stevens 555 Sporting O/U?
The Sorix is objectively superior for dynamic, high-volume waterfowl shooting where reliability under fouling is paramount, while the Stevens 555 Sporting 20 Gauge offers better suitability for controlled-pass sporting clays. The Sorix’s inertial semi-auto system will cycle hundreds of rounds with minimal cleaning—a critical advantage in a muddy marsh—whereas the Stevens O/U requires manual operation, limiting shot speed but providing instant visual chamber verification. For a waterfowl hunter facing a limit, the Sorix’s capacity and faster follow-up shots are decisive.
What does it weigh and what are the dimensions?
The Sorix Slough weighs exactly 6.5 pounds unloaded, with a 28-inch vent-rib barrel contributing to a 48.5-inch overall length. The length of pull is adjustable via shims from 14.25 to 14.75 inches, a 0.5-inch range critical for proper fit with layered winter clothing. The forend measures 1.75 inches in diameter at its widest point, providing a secure grip without excessive bulk for smaller-handed shooters often drawn to the 20-gauge platform.Who is this NOT for?
This is not a suitable firearm for tactical or home-defense applications. The limited 2+1 capacity and lack of accessory rail or threaded barrel for a choke tube extension make it a poor choice for competition 3-gun or defensive use. Hunters requiring extreme long-range capability with specialized, non-standard chokes will also find the included five-choke system insufficient compared to dedicated target shotguns offering extended, ported tubes.
What's in the box?
You receive the complete shotgun, five Benelli Crio Plus choke tubes (Cylinder, Improved Cylinder, Modified, Improved Modified, Full), three stock shims for adjusting drop and cast, and the appropriate choke tube tool. Weatherby includes a single, plastic stock spacer for length-of-pull adjustment, but serious shooters will require aftermarket kits to achieve the full published adjustment range. The manual contains clear NFA-compliance warnings regarding overall length, which remains well above the 26-inch federal minimum for shotguns.
Is the Weatherby Sorix Slough worth it at $1324.99?
At $1324.99, the Sorix Slough is a justified investment for the dedicated waterfowler who values bombproof reliability over cosmetic features. You are paying for a licensed, proven inertial system wrapped in a purpose-built hunting stock, not hand-checkering or exotic wood. Compared to the base price of a true Benelli M2 or Franchi Affinity in similar configuration, the Sorix represents a $200-$300 savings while delivering nearly identical mechanical performance in the field—a direct trade of brand prestige for functional value. For the budget-conscious hunter considering our Stevens 334 Rifle for big game, this shotgun occupies the same utilitarian niche for wingshooting.

Pros & cons
What works
- Inertia-driven action cycles 7/8 oz. target loads to 3" magnums unfailingly—zero adjustments required.
- Weighs 6.5 lbs—1.5 lbs lighter than a typical gas-operated 12-gauge semi-auto, reducing fatigue in the field.
- Includes five genuine Benelli Crio Plus choke tubes (C, IC, M, IM, F) for immediate pattern versatility.
- SHIFT System provides true ambidextrous safety and bolt release without compromising grip geometry.
Trade-offs
- Fixed 2+1 capacity—cannot accept tube extensions, limiting utility for high-volume clay games.
- Slough camo is a printed finish, not a dipped hydrographic; expect minor wear on high-contact areas after 2-3 seasons.
- Stock shim system is basic; achieving precise comb height requires aftermarket cheek risers not included.

Frequently asked questions
- Does this work with standard Benelli Crio Plus chokes?
- Yes, the Sorix barrel is threaded for genuine Benelli Crio Plus choke tubes, and the system includes five factory tubes. Aftermarket Crio Plus tubes from Carlson's, Briley, and Trulock will thread directly into the barrel without modification, maintaining the 0.725-inch internal constriction at the muzzle.
- Is it compatible with a magazine tube extension?
- No. The Sorix uses a non-removable magazine tube that is integral to the forend assembly, prohibiting the installation of aftermarket extensions. The fixed 2+1 capacity is a deliberate design choice by Weatherby to maintain the shotgun's hunting profile and ensure reliable spring tension across all shell lengths up to 3 inches.
- How long does shipping take to an FFL?
- Processing and shipping to your selected FFL dealer typically takes 3-5 business days from order verification. All shipments require signature confirmation at the FFL and compliance with a mandatory 72-hour hold after the background check is initiated, as per our standard firearms transfer protocol.
- Can I return it if the fit is wrong?
- You cannot return the shotgun due to incorrect fit after the transfer is complete, as federal law prohibits FFLs from accepting returns of firearms from non-licensees. We strongly recommend using the included shim kit to adjust drop and cast before finalizing the transfer at your dealer to ensure proper ergonomics.
