Diamondback Sdr Stainless 38 Spl 357 Mag 2 Barrel 6 Rounds 2

About this product

The Diamondback SDR is a compact stainless-steel revolver chambered for .357 Magnum and .38 Special +P, giving owners the flexibility to practice with milder .38 Special loads and carry full-power .357 Magnum for defense. This listing is the 2-inch barrel, 6-round configuration priced at $648.

What does the SDR bring to the small-frame revolver category?

Diamondback built the SDR with a forged stainless steel frame and a 2-inch stainless barrel, keeping overall length to 6.53 inches and weight to 21.2 ounces — light enough for pocket or ankle carry, but with enough mass to help manage .357 Magnum recoil better than an ultra-lightweight alloy-frame snub revolver. The rounded frame profile and concealed hardware are specifically designed to reduce snagging during a draw from concealment, a detail that matters more on a carry revolver than a range gun.

What are the sights and trigger like?

The SDR uses a two-color fiber-optic sight setup — orange front, green rear — which makes for faster sight acquisition than plain black sights, especially indoors or in low light where a snub revolver is most likely to be used defensively. It runs a double-action/single-action match-grade trigger, with a double-action pull in the 9-11.5 pound range and a crisp single-action break around 3.5 pounds, giving shooters the option of either a full double-action trigger pull per shot or cocking the hammer for a lighter, more precise single-action shot.

How easy is it to maintain?

Diamondback designed the cylinder and crane assembly to come out as a single unit with the press of a button, letting owners scrub the forcing cone and chamber faces without having to work tools around the frame the way many revolvers require. That's a genuinely useful feature for a carry gun that sees regular cleaning after range sessions or carry rotation.

How much does it actually weigh, and does that matter for carry?

At 21.2 ounces unloaded, the SDR sits in a middle ground between ultra-light alloy-frame revolvers (which can feel unpleasant to shoot with full-power .357 loads) and heavier all-steel service revolvers. That weight is part of why Diamondback markets it as capable of handling .357 Magnum rather than being limited to .38 Special — a lighter gun in this exact size class often restricts owners to .38 Special only for comfortable shooting.

What should California buyers confirm?

Confirm current California handgun roster status for the Diamondback SDR with your FFL before ordering, along with the specific finish (this listing is stainless; Diamondback also offers Black Nitride+ and glass-bead finishes) available for California sale. As a firearm, it transfers through your chosen licensed FFL dealer rather than shipping to your home.

How does a 2-inch barrel affect .357 Magnum performance?

Full-power .357 Magnum loads are designed and typically tested out of 4- to 6-inch barrels, and a 2-inch snub barrel like this one gives up a meaningful amount of that velocity — along with producing significantly more muzzle flash and blast, since much of the powder charge burns outside the shorter barrel. That's a normal tradeoff for the concealability a 2-inch barrel provides, and it's part of why many owners carry .357 Magnum in this size gun for the option, while practicing primarily with milder .38 Special loads that don't lose as much performance from the shorter barrel, keeping range sessions comfortable without giving up the option to load full-power magnum rounds for carry.
