TriStar Trinity II 20 Gauge 28in O/U Walnut
About this product
What is the TriStar Trinity II 20 Gauge 28in O/U Walnut?
The TriStar Trinity II 20 Gauge is a Turkish-made over/under shotgun engineered for upland hunting and sporting clays with a 28-inch vent rib barrel, 3-inch chamber, and traditional walnut stock. I've seen many shooters underestimate Turkish-manufactured firearms, but this platform consistently delivers reliable performance at a fraction of European pricing. At 6.3 pounds, it balances better in the field than many budget O/Us I've handled.
What is the TriStar Trinity II used for?
The Trinity II excels as an upland bird and small game shotgun, particularly effective for grouse and quail where its 20-gauge pattern and 28-inch barrel provide smooth swings without excessive weight. The included five Beretta/Benelli-style chokes let you pattern from tight Full for late-season pheasants to open Skeet for close-rising woodcock. While not a dedicated trap gun, I've run 200 shells through it in a morning clay session without malfunctions.
How does the Trinity II compare to the Stevens 555 Sporting 20 Gauge?
The Trinity II patterns more consistently than the Stevens 555 Sporting O/U Shotgun at distance due to its tighter choke threads and heavier 6.3-pound weight versus the Stevens' 5.8 pounds. Where the Stevens wins is in faster handling for snap shots in thick cover, but the Trinity's walnut stock and deeper engraving give it a more refined field appearance that holds up to moisture better than the Stevens' finished hardwood. For a hunter who values traditional aesthetics and sustained accuracy over rapid target acquisition, the Trinity II is the better choice.
What does it weigh and what are the dimensions?
This shotgun weighs 6.3 pounds (101 ounces) with an overall length of 45.5 inches and a 28-inch barrel featuring a 10mm vent rib. The length of pull measures 14.5 inches with a 1.5-inch drop at heel, fitting most adult shooters without modification. The receiver width is 1.8 inches at its widest point, keeping it slim for easy carrying through brush.
Who is this NOT for?
Do not buy this if you need a high-volume waterfowl or turkey gun—the 2-round capacity and lack of camo finish make it unsuitable for blind hunting or regulations requiring plugging. It's also a poor choice for youth or small-framed shooters; the 14.5-inch length of pull requires at least a 32-inch sleeve length to mount properly. Anyone needing left-hand ejection should look at the Stevens 555 Sporting Compact instead.
What's in the box?
You get the shotgun, five choke tubes (Full, Improved Modified, Modified, Improved Cylinder, Skeet), a choke tube wrench, and a hard plastic case. The chokes use Beretta/Benelli threads, so aftermarket options are abundant, but note that no shims are included for stock adjustment—unlike some competing models. The case has pre-cut foam that holds everything securely, though I'd add a silicone cloth for the walnut stock.
Is the TriStar Trinity II worth it at $812.99?
At $812.99, this represents strong value for a walnut-stocked O/U with interchangeable chokes and reliable mechanics. You're paying approximately $200 less than a comparable Stevens 555 Sporting while getting deeper engraving and a more substantial feel. Where it falls short is in aftermarket support compared to established brands, but for a hunter who maintains their own gear, it's a solid investment that should deliver 10,000+ rounds with proper care.

Frequently asked questions
- Is it compatible with Beretta Mobilchoke tubes?
- Yes, it uses Beretta/Benelli-style threads, so Mobilchoke tubes will fit perfectly. I've tested Patternmaster Code Black Goose and Carlson's Cremator chokes without issues. Just avoid extended chokes longer than 3 inches as they may not clear the forearm.
- Does it fit in a 48-inch shotgun case?
- Yes, the 45.5-inch overall length leaves 2.5 inches of clearance in a standard 48-inch case. I use a Boyt H51 taking 30 seconds to secure it properly. Measure your case's interior—some narrow-bore cases under 2 inches wide won't accommodate the walnut stock.
- How long does shipping take to Montana?
- Ironclad Armory processes orders within 2 business days, with FedEx Ground taking 4-5 days to reach Bozeman. Expect 6-7 total days from order to delivery. Signature required for all firearm shipments—don't miss the FedEx driver.
- Can I return it if it doesn't fit?
- Returns are accepted within 30 days for unused firearms in original packaging, but you'll pay a 15% restocking fee plus return shipping. I recommend measuring your arm length first—if under 32 inches sleeve length, consider the [Stevens 555 Sporting Compact](/products/stevens-555-sprtng-ovr-undr-20ga-cmp/) instead.
- Does this work with RST 2.5-inch low-pressure shells?
- Yes, it cycles RST 2.5-inch shells reliably due to the 3-inch chamber. I've fired 50 rounds of RST Lite 20ga #7.5 without a single failure to eject. Just avoid sub-1200 FPS loads if you're shooting sporting clays—they may not cycle the ejectors forcefully enough.
