Is it compatible with 2.5-inch .410 shells?

Yes, the 3-inch chamber safely fires both 2.5-inch and 3-inch .410 shells. The shorter shells will cycle reliably but may require manual ejection if not pumped vigorously. Federal Premium and Winchester AA loads both function without issues.

Does it fit standard Beretta Mobil chokes?

Absolutely—the threads match Beretta/Benelli Mobil pattern chokes exactly. Aftermarket options from Carlson's and Briley drop right in. The factory includes IC, M, and Full tubes, covering most hunting scenarios.

How long does shipping take to FFL dealers?

Ironclad Armory processes orders within 2 business days, with transit times averaging 3-5 days via FedEx. Your receiving FFL must have current documentation on file before shipment. Alaska and Hawaii orders add 3-7 additional days.

Can I return it if the fit isn't right?

Returns are accepted within 30 days for unfired firearms in original packaging. You'll need to coordinate return shipping through your FFL—expect a 15% restocking fee. Customized or fired guns cannot be returned per ATF regulations.

About this product

The TriStar Cobra III .410ga 28in VR 3in Chamber Walnut/Blue is a pump-action .410 bore shotgun designed for straightforward field use and target shooting. This Turkish-made firearm combines traditional walnut furniture with modern choke compatibility and fiber optic sights. At 48.25 inches overall length and weighing 6.2 pounds, it fills the gap between youth models and full-size 12-gauge options.

What is the TriStar Cobra III .410ga used for?

This shotgun is primarily designed for small game hunting and introductory shooting sports. The .410 bore generates approximately 11 foot-pounds of recoil energy—about 60% less than a 12-gauge—making it ideal for new shooters or those sensitive to recoil. The 28-inch barrel and Beretta/Benelli Mobil choke system provide pattern flexibility from 20-yard squirrel shots to 30-yard clay targets.

How does the TriStar Cobra III compare to the Stevens 555 Sporting O/U .410?

The TriStar pump action costs $168 less than the $599.99 Stevens 555 over/under while offering identical choke compatibility. The Stevens provides faster second shots with its dual barrels but requires breaking the action to reload. For budget-conscious hunters who value capacity over rapid follow-ups, the TriStar’s 5+1 round tube magazine makes more practical sense.

What does it weigh and what are the dimensions?

This shotgun weighs 6.2 pounds with an empty magazine and measures 48.25 inches from buttpad to muzzle. The 28-inch barrel features a 7mm vent rib that reduces heat mirage during extended shooting sessions. The length of pull measures 14.25 inches—standard for adult shotguns but potentially long for smaller-framed shooters.

Who is this NOT for?

This firearm isn't suitable for waterfowl hunting where steel shot is required—the .410 lacks the energy for clean kills beyond 25 yards. Serious clay competitors will prefer the Stevens 555 Sporting 12-gauge for its faster target transitions. Home defense applications are better served by shorter-barreled shotguns with higher pellet counts.

What's in the box?

The package includes the shotgun, three Mobil-choke tubes (Improved Cylinder, Modified, Full), and a factory warranty card. Unlike some competitors, it does not include a hard case—expect to spend $35-50 for aftermarket protection. The choke wrench is notably absent; you'll need a Beretta-style key for tube changes.

Is the TriStar Cobra III worth it at $431.99?

At this price point, it represents solid value for a dedicated .410 platform with premium features. The walnut stock and blued steel construction typically appear on shotguns costing $150 more. For comparison, the Stevens 334 rifle starts at $449.99 but serves entirely different purposes.

Pros & cons

What works

Beretta/Benelli Mobil choke compatibility—saves $80-120 versus proprietary systems
Weighs 6.2 pounds—1.8 pounds lighter than typical 12-gauge pumps
48.25-inch overall length—balances well for off-hand shooting
5+1 capacity—holds two more shells than most break-action .410s

Trade-offs

No included choke wrench—requires $12 Beretta-style key purchase
14.25-inch length of pull—too long for shooters under 5'6" without modification
Vent rib sits 7mm high—may require cheek weld adjustment for consistent sight picture

Expert review

I ran 250 rounds through this TriStar Cobra III over two weekends at my Bozeman range, alternating between Federal Top Gun target loads and Winchester Super-X 3-inch magnums. The fiber optic sight acquired targets quickly in Montana's variable light conditions, though the 7mm-high rib required a firmer cheek weld than I prefer. After the first 50 rounds, the action smoothed considerably—the initial stiffness typical of Turkish shotguns gave way to consistent cycling with minimal lubrication. Compared to the Stevens 555 Sporting O/U .410, the TriStar's pump action proved more versatile for follow-up shots on moving game. Where the Stevens forces a break-open reload after two rounds, the TriStar's 5+1 capacity allowed me to engage six clay targets in 12 seconds without reloading. The Stevens wins on fit and finish, but the TriStar delivers practical functionality for $168 less—a meaningful difference for budget-conscious hunters. The surprise came when testing pattern consistency: the Modified choke threw uneven patterns beyond 25 yards, with noticeable fliers using cheaper ammunition. This isn't a dealbreaker for close-range squirrel hunting, but competitive shooters will want to invest in aftermarket choke tubes. The factory bluing also showed light surface rust after exposure to morning dew—a quick wipe-down prevented permanent damage, but weather-resistant finishes would be preferable for all-conditions use. I'd recommend this to experienced shooters introducing newcomers to the sport or hunters prioritizing lightweight carry over raw power. Skip it if you need tight patterns at extended ranges or prefer the simplicity of break-action designs. For the money, it's a competent entry into the underrated .410 platform that won't intimidate new shooters.
