Weatherby Sorix Storm 12ga Semi-Auto 3.5″ 28″ Synthetic
About this product
The Weatherby Sorix Storm 12ga Semi-Auto 3.5" 28" Synthetic is a 12-gauge, inertia-driven semi-automatic shotgun engineered for demanding waterfowl environments where reliability under harsh conditions is non-negotiable. This platform balances a 7.1 lb unloaded weight with a 28-inch barrel to manage 3.5-inch magnum loads, a combination that speaks to hunters prioritizing pattern consistency at extended ranges over quick-handling maneuverability. It arrives with the Benelli Crio Plus choke system and a synthetic Storm camo stock featuring adjustable shims for a custom fit, positioning it as a dedicated tool for serious migratory bird hunters.
What is the Weatherby Sorix Storm 12ga Semi-Auto used for?
This shotgun is purpose-built for waterfowl and extended-range upland bird hunting where 3.5-inch magnum steel or heavy lead shot loads are standard. Its 28-inch vent-rib barrel and included five-choke system (C, IC, M, IM, F) are optimized for creating dense, consistent patterns at 40+ yards, making it ideal for pass-shooting geese or ducks over decoys. The synthetic stock and corrosion-resistant internal components are designed to withstand the salt marsh, blind, and foul-weather conditions that quickly degrade less robust platforms.
How does the Weatherby Sorix Storm compare to a Stevens 555 Sporting O/U?
The Sorix Storm outperforms a break-action like the Stevens 555 Sporting O/U in rapid follow-up shot capability and high-volume shell handling, but at the cost of added mechanical complexity. Where the Stevens 555 offers immediate, intuitive barrel selection with its twin triggers and simple 3-inch chamber, the Sorix Storm's semi-auto action allows for a faster second or third shot on flushing birds, a critical advantage in high-density waterfowl scenarios. However, the Sorix's inertia system requires more frequent and specific maintenance than the Stevens' straightforward break-action design.
What does the Weatherby Sorix Storm weigh and what are its dimensions?
The Sorix Storm has an unmistakeably long and lean profile, with an overall length of approximately 48.5 inches driven by its 28-inch barrel and an unloaded weight of 7.1 lbs (113.6 oz). Its 14.75-inch length of pull, adjustable via included shims, accommodates most adult shooters wearing bulky winter or wader gear. The balance point sits roughly 3 inches forward of the receiver, a design choice that stabilizes the swing but makes the gun feel every bit of its near-50-inch total length when navigating thick cover or a cramped blind.
Who is the Weatherby Sorix Storm NOT for?
This is a poor choice for hunters prioritizing fast handling in tight quarters, such as for ruffed grouse in alder thickets or turkeys in heavy timber. The 28-inch barrel and 48.5-inch overall length create significant swing inertia, making quick snap-shots difficult compared to a shorter-barreled model like the Stevens 334 Rifle in a hunting context. It's also not ideal for a new shooter sensitive to recoil, as its 3.5-inch chamber and 7.1 lb weight mean it will be punishing with heavy magnum loads, despite the included recoil pad.
What's in the box with the Weatherby Sorix Storm?
You receive a complete, field-ready shotgun system. The core package includes the synthetic-stocked Sorix Storm shotgun, five Benelli Crio Plus choke tubes (Cylinder, Improved Cylinder, Modified, Improved Modified, Full), a choke tube wrench, three stock adjustment shims for altering cast and drop, and an owner's manual detailing the specific 500-round break-in procedure. Notably absent is any form of case or storage solution; Weatherby assumes the serious hunter purchasing this platform already possesses dedicated protective transport.
Is the Weatherby Sorix Storm worth it at $1569.99?
At $1569.99, the Sorix Storm justifies its price for the waterfowl specialist who will exploit its full capabilities: the 3.5-inch chamber, ambidextrous SHIFT controls, and robust inertia system built for relentless, wet conditions. You are paying for a duty-grade action in a hunting chassis, not for fancy wood or cosmetic finishes. For the hunter who only occasionally hunts waterfowl or who primarily uses 2.75-inch or 3-inch shells, a more affordable semi-auto or a reliable over/under like the Stevens 555 series will deliver 90% of the performance for significantly less capital outlay.

Pros & cons
What works
- Handles 3.5-inch magnums reliably – built for the heaviest waterfowl loads
- Includes 5 Benelli Crio Plus choke tubes (C, IC, M, IM, F) – a $125+ value
- Ambidextrous SHIFT controls – fully operable from either shoulder
- Synthetic stock with 3 adjustment shims – allows precise length-of-pull and cast/drop tuning
Trade-offs
- Proprietary choke system (Benelli Crio Plus) – limits aftermarket tube options and increases replacement cost
- Long 48.5" overall length – cumbersome in tight blinds or thick cover
- Requires specific 500-round break-in with full-power ammo – adds significant initial cost and time
- No storage case included – requires separate purchase for transport

Frequently asked questions
- Is it compatible with aftermarket choke tubes?
- No, it is not universally compatible. The Sorix Storm uses the proprietary Benelli Crio Plus choke system thread pattern. You must purchase Crio Plus-compatible tubes from Benelli, Weatherby, or select aftermarket manufacturers like Carlson's or Briley, which typically cost $25-$50 per tube.
- Does this model have a threaded barrel for a choke tube or suppressor?
- Yes, it has a threaded muzzle for the included Benelli Crio Plus choke tubes, but it is not threaded in the metric or imperial pattern required for a shotgun suppressor (like a SilencerCo Salvo 12). The threads are choke-specific and cannot be adapted for a suppressor without significant, warrant-voiding gunsmithing work.
- Can the stock be swapped for a pistol grip or adjustable model?
- Potentially, but not without research. The Sorix Storm uses a proprietary receiver interface. Aftermarket stock options are limited compared to the ubiquitous Remington 870 or Mossberg 500. Check with Mesa Tactical or Boyd's for specific adapter kits, which can add $150-$300 and require fitting.
- How long is the shipping time for an online order?
- Shipping to your licensed FFL dealer typically takes 3-7 business days from Ironclad Armory's warehouse after payment and compliance verification are complete. Your FFL will then initiate the mandatory 4473 background check, which adds a variable wait time depending on state laws and NICS delays.
- What is the recommended break-in procedure?
- Weatherby's manual specifies a 500-round break-in using full-power 2.75-inch or 3-inch target or field loads (minimum 1 1/8 oz shot at 1200 fps). Do not use light target loads or 3.5-inch magnums during this period. This cycles the action under consistent pressure, ensuring reliable function with all loads thereafter.
