Weatherby Sorix Slough 20 Gauge 28″ Semi-Auto

The Weatherby Sorix Slough 20 Gauge 28″ Semi-Auto is an inertia-driven shotgun built for hunters who refuse to compromise on fit or function. It pairs a 28-inch vent-rib barrel with the Benelli Crio Plus choke system and ships with multiple tubes, letting you dial in patterns for waterfowl, upland, or turkeys. Ambidextrous controls via the SHIFT System and adjustable stock shims mean this gun adapts to you—not the other way around. At 5.8 pounds (per manufacturer specs), it swings fast and carries easy through a long day in the marsh or the field.

Key Features

• Inertia-Operated Action – why it matters: fewer moving parts mean cleaner cycling in mud, snow, or sand, with less recoil than gas guns.
• Benelli Crio Plus Choke System – why it matters: cryogenically treated tubes deliver tighter, more consistent patterns and resist fouling longer.
• SHIFT System Ambidextrous Controls – why it matters: safety and bolt release are reversible, so lefties and righties share the same platform without compromises.
• Adjustable Stock Shims – why it matters: cast, drop, and pitch are tunable in minutes, letting you dial in perfect mount and eye alignment.
• Slough Camo Finish – why it matters: the pattern breaks up your outline in flooded timber and marsh grass, and the coating resists corrosion from saltwater and mud.

Who It’s For

This shotgun is for waterfowlers who demand reliability in harsh conditions and want a lightweight 20-gauge that doesn’t beat you up. It’s also a strong pick for upland hunters who cover ground and need fast, pointable handling. If you’re a shooter who likes to tune your gear—shims, chokes, controls—the Sorix gives you that flexibility out of the box.

Pros & Cons

• Pro: 5.8-pound weight makes it one of the lightest inertia 20-gauges in its class—easier to carry all day.
• Pro: Crio Plus chokes tighten patterns noticeably vs. standard tubes (verified in field tests).
• Con: Inertia guns can be picky with light target loads; you’ll want to run at least 1-oz or 1,200+ fps loads for reliable cycling.
