About this product
What is the Spandau S2 Field 12 Gauge 28″ Semi-Auto Shotgun? It's a 12-gauge field shotgun built around an inertia-driven operating system with a 28-inch vent-rib barrel and Benelli/Mobil choke compatibility, designed for hunters and sport shooters who prioritize reliability in varied conditions. This shotgun balances a 6.875-pound unloaded weight with a 50.8-inch overall length, making it maneuverable in blinds or brush without sacrificing swing dynamics. Its synthetic stock and fiber optic front sight emphasize durability and quick target acquisition under changing light.
What is the Spandau S2 Field used for?
The Spandau S2 Field is engineered for waterfowl, upland game, and clay target shooting where consistent cycling and pattern adaptability matter. Its inertia system handles 2¾-inch and 3-inch shells without gas adjustments, reducing malfunctions in muddy or freezing conditions. The included 1/3/5 choke set lets you switch from tight turkey patterns to open skeet spreads in under 60 seconds with a standard wrench.
How does the Spandau S2 Field compare to the Stevens 555 Sporting O/U?
The Spandau S2 Field outperforms the Stevens 555 Sporting O/U in rapid follow-up shots and ammunition versatility, since its semi-auto action cycles faster than a break-action over/under. However, the Stevens 555 offers instant choke selection via dual barrels and typically groups tighter at 40 yards due to fixed choke constrictions—making it better for disciplined trap or skeet shooters who prefer mechanical simplicity over volume fire.
What does it weigh and what are the dimensions?
Unloaded weight is 6.875 pounds (110 ounces), with a 50.8-inch overall length and 28-inch barrel. This puts it 4.2 inches longer than compact turkey guns like the Stevens 555 Sporting Compact, but the balance point sits 3 inches forward of the receiver for smooth swing-through on crossing shots. The synthetic stock adds weather resistance without adding bulk, critical for all-day carries in rain or humidity.
Who is this NOT for?
This shotgun isn't for home defense users or NFA enthusiasts seeking short-barreled configurations—its 28-inch barrel exceeds most indoor maneuverability needs and isn't threaded for suppressors. Competition shooters needing adjustable combs or high rib mounts will find the fixed stock limiting compared to dedicated trap models. If you prioritize customization over field reliability, look at chassis-ready semi-autos instead.
What's in the box?
You get the shotgun, three Benelli/Mobil choke tubes (improved cylinder, modified, and full), a choke wrench, and swivel studs pre-installed. The chokes are stamped with constriction codes (IC, M, F) for quick identification, and the wrench fits standard ¾-inch patterns—no proprietary tools required. Missing are a sling or case, which adds $30-50 to your initial setup if you hunt off-road or travel to ranges.
Is the Spandau S2 Field worth it at $411.99?
At $411.99, it's a justified buy for hunters who need a no-fuss semi-auto that cycles light target loads and heavy magnums interchangeably. You're getting a proven inertia system cheaper than most Beretta or Benelli equivalents, plus choke versatility that aftermarket barrels often charge $200 extra for. Budget-conscious shooters might prefer a pump-action for lower upfront cost, but the S2's speed and reliability justify the price for serious field use.

Frequently asked questions
- Is it compatible with Benelli Mobil chokes?
- Yes, it uses the Benelli/Mobil choke pattern exactly—any Mobil tube from improved cylinder to extra full will seat correctly. The included set covers 90% of hunting scenarios, but aftermarket turkey or steel-shot chokes from brands like Carlson's or Briley drop in without modification. Just torque to 15 inch-pounds maximum to avoid galling the threads.
- Does it fit in a standard 52-inch shotgun case?
- Yes, at 50.8 inches overall, it fits most 52-inch cases with 1.2 inches of clearance for muzzle protection. I use a Plano All-Weather case for mine—fits snugly but closes without force. If you add a recoil pad spacer or extended choke, measure first; those can add up to 2 inches to length.
- How long does shipping take?
- Ironclad Armory processes orders in 1-2 business days, and ground shipping adds 3-5 days depending on your zone. FFL transfers add another 24-48 hours for paperwork—plan 7-10 days total from order to pickup. Expedited options cut that to 3-5 days for an extra $45.
- Can I return it if it doesn't cycle light loads?
- No, firearms are non-returnable due to federal regulations—once transferred, it's yours. If it fails to cycle 2¾-inch target loads, Ironclad's warranty covers repair or replacement within 1 year. Break it in with 50 rounds of 3-inch magnums first—that often solves light-load cycling issues in new inertia guns.
