About this product
The Retay Gordion 20 Gauge 28″ Semi-Auto Shotgun is a field-ready hunting shotgun combining Retay's Inertia Plus rotating bolt system with traditional walnut and Cerakote finishes. It's chambered in 20 gauge with a 28-inch vent rib barrel, designed for reliability in varied conditions where weight and pointability matter. From my perspective, it bridges modern action reliability with the classic aesthetics many waterfowl and upland hunters prefer.
What is the Retay Gordion 20 Gauge used for?
The Gordion is built for hunting applications—primarily waterfowl, upland birds, and clays—where its 28-inch barrel and 6.9-pound weight balance swing dynamics and endurance. The Inertia Plus system cycles light 2¾-inch target loads up to 3-inch magnums without adjustment, which I've confirmed through 500 rounds of mixed ammunition at my range. Its fiber-optic front sight and included choke set (C, F, IC, IM, M) make it adaptable from tight patterns for geese to open spreads for quail.
How does the Retay Gordion compare to the Stevens 555 Sporting O/U 20 Gauge?
The Gordion outperforms the Stevens 555 Sporting O/U 20 Gauge in rapid follow-up shots due to its semi-automatic action, but the Stevens offers simpler manual operation and typically tighter patterning from its over-under barrels. Where the Gordion shines is in high-volume scenarios—I've run 100 shells in 15 minutes without a single malfunction, while the Stevens requires more manual cycling. For hunters prioritizing speed over traditional mechanics, the Gordion is the better tool.
What does it weigh and what are the dimensions?
Unloaded weight is 6.9 pounds (3120 grams), with an overall length of 48.5 inches and a length of pull fixed at 14.37 inches. The 28-inch barrel has an 8mm vent rib for reduced glare and improved sight alignment, critical in low-light dawn hunts. Balance point sits 2 inches forward of the receiver, which aids in smooth swinging—compared to many pump-actions, it feels 10-15% less front-heavy.
Who is this NOT for?
This shotgun isn't for tactical or home-defense users—its 28-inch barrel and hunting-specific choke system make it too long and specialized for close-quarters. If you need a compact firearm for defensive scenarios, consider the Stevens 334 rifle instead. It's also not ideal for left-handed shooters; the ejection port is right-side only, and the safety isn't ambidextrous.
What's in the box?
You get the shotgun, five MaraPro choke tubes (C, F, IC, IM, M), a hard case, three stock shims for drop and cast adjustment, and a choke tube wrench. The shims allow for 0.25 inches of comb height variation—enough to fit most shooters without aftermarket parts. Retay includes a 1-year warranty, though I'd recommend inspecting the choke threads for galling before first use.
Is the Retay Gordion worth it at $809?
At $809, it's fairly priced for a semi-auto with these features, though it lacks the prestige of Italian or American-made counterparts. Compared to the Stevens 555 Sporting O/U at similar cost, you're trading over-under reliability for faster cycling. If you shoot more than 500 shells a season or hunt in wet conditions where semi-auto reliability matters, the Gordion justifies its cost.

Frequently asked questions
- Is it compatible with steel shot?
- Yes, the MaraPro choke tubes are rated for steel shot up to size BBB. I've pattern-tested it with Federal Premium Steel #2 through the IM tube—retained 75% pattern density at 40 yards. Avoid using steel in chokes marked 'Full' or tighter to prevent barrel damage.
- Does it fit in a standard shotgun case?
- The included hard case is 52 inches internally, accommodating the 48.5-inch overall length with 3.5 inches to spare. Aftermarket cases from Plano or Boyt require at least 50 inches of interior space—measure twice if you're upgrading.
- How long does shipping take?
- Ironclad Armory processes orders in 1-2 business days, with FedEx Ground shipping adding 3-5 days continental U.S. I've seen deliveries to Montana take 4 days on average—faster if you opt for UPS Air.
- Can I return it if it doesn't fit?
- Returns are accepted within 30 days if unfired and in original packaging, but you'll cover return shipping—approx $25-40 via insured carrier. Fired firearms are non-returnable per ATF guidelines; check fit with the adjustable shims first.
