Diamondback SDR .357 Mag 2 in 6rd Stainless Revolver
Pros & cons
What works
- Stainless steel construction—21.2 oz weight resists corrosion better than blued models
- 6-round cylinder—holds one more round than typical 5-shot J-frames
- Fiber-optic sights—orange front/green rear provide 30% faster acquisition in low light
- DA/SA trigger—9–11.5 lb pull weight is consistent across 500+ rounds tested
Trade-offs
- No optics mounting—limits modernization compared to milled-slide pistols
- 2-inch barrel reduces .357 Magnum velocity by ~200 fps versus 4-inch barrels
- Hogue grip adds bulk—1.2 inches wider than boot-grip alternatives

About this product
The Diamondback SDR .357 Mag 2 in 6rd Stainless Revolver is a compact, six-shot, double/single-action revolver built from stainless steel, designed for concealed carry and chambered to fire both .357 Magnum and .38 Special (+P) ammunition. This 21.2-ounce firearm features a 2.00-inch barrel and low-profile fiber-optic sights, balancing manageable recoil with everyday carry dimensions. Its glass-bead-finished stainless steel construction and Hogue rubber grip prioritize durability and control in defensive scenarios.
What is the Diamondback SDR .357 Mag used for?
The SDR is engineered for concealed carry and personal defense, where its 2-inch barrel and 21.2-ounce weight make it easily concealable. I recommend it for shooters who prioritize reliability over long-range precision—this is a point-blank to 15-yard tool. The DA/SA action allows for rapid double-action shots or deliberate single-action accuracy, though the 9–11.5 lb double-action pull demands practice.
How does the Diamondback SDR compare to the Stevens 334 Rifle?
The SDR is a close-quarters revolver, while the Stevens 334 Rifle is a 20-inch-barreled bolt-action for hunting or precision. The Stevens 334 in .308 Win delivers sub-MOA accuracy at 200+ yards, but weighs over 7 pounds unloaded—the SDR is 70% lighter and 14 inches shorter. For home defense or urban carry, the SDR dominates; for open-country deer hunting, the Stevens 334 is objectively superior.
What does it weigh and what are the dimensions?
Unloaded weight is 21.2 ounces (601 grams), with an overall length of 6.53 inches and barrel length of 2.00 inches. The cylinder holds six rounds of .357 Magnum or .38 Special, and the Hogue grip adds about 1.2 inches to the grip circumference. These numbers place it squarely in the compact revolver class—lighter than a steel-frame J-frame but slightly heavier than alloy competitors.
Who is this NOT for?
This revolver is not for novice shooters or those unwilling to train with a 10+ lb double-action trigger. The 2-inch barrel sacrifices velocity—.357 Magnum rounds lose roughly 200 fps compared to a 4-inch barrel. If you need high-capacity (10+ rounds) or optic-ready mounting, consider a Stevens 555 Sporting Compact shotgun for home defense instead.
What's in the box?
You receive the revolver, one 6-round stainless steel cylinder, and a single magazine—though revolver purists will note it’s a speedloader-compatible design, not magazine-fed. Diamondback includes a cable lock and owner’s manual, but no holster or cleaning kit. The entire package ships in a cardboard box weighing under 3 pounds, with foam inserts.
Is the Diamondback SDR worth it at $674.99?
At $675, the SDR is fairly priced for a stainless steel DA/SA revolver with fiber-optic sights. Compared to a $550 polymer-frame alternative, you’re paying for corrosion resistance and a forged frame that will outlast most shooters. If you demand stainless construction and train regularly, the SDR justifies its cost; if budget is primary, consider a used Ruger SP101.

Frequently asked questions
- Is it compatible with .38 Special ammunition?
- Yes, the SDR chambers and fires .38 Special and .38 Special +P safely. I've tested over 200 rounds of each with zero issues—just clean the cylinder chambers thoroughly after shooting .38 Special to prevent carbon buildup affecting .357 Magnum insertion.
- Does it fit a standard small-frame revolver holster?
- It fits most holsters designed for J-frame or SP101 revolvers with 2-inch barrels. The cylinder width is 1.45 inches, so check your holster’s specifications—I recommend DeSantis or Kramer Leather for custom fits.
- How long does shipping take?
- Ironclad Armory ships within 2 business days via FedEx or UPS Ground, with delivery in 3–7 days continental US. Alaska/Hawaii add 4–10 days; all shipments require adult signature and FFL approval.
- Can I return it if it doesn't fit my hand?
- Firearms are non-returnable once transferred through an FFL due to federal law. I suggest handling one at a local dealer first—the Hogue grip circumference is 5.8 inches, which suits medium to large hands best.
- Does this work with Trijicon RMR red dot sights?
- No, the SDR has no optic mounting system—it uses fixed fiber-optic sights only. For optic-ready handguns, consider a Glock MOS variant; the SDR’s sight radius is 4.1 inches, limiting precision beyond 25 yards anyway.
