Florida-based Diamondback Firearms continues to build out its line of snub-nosed defensive revolvers with a new lightweight model for 2026. 

The double-action-only SDR-A uses a forged 7075-T6 aluminum frame to trim weight to just under a pound (15.6 ounces) while maintaining rigidity under recoil. Combined with a stainless steel six-shot fluted cylinder and 2-inch barrel, Diamondback says the new offering delivers long-term durability in a lightweight package. It has a non-stacking trigger in the 9-to-11-pound range.

The SDR-A weighs just under a pound and has an overall length of 6.70 inches. The platform is rated for 38 SPL +P, and has a six-shot cylinder, a substantial difference from many comparable designs that only carry five. (Photos: Diamondback)

It has a glass bead DBGuard finish and uses a fixed green fiber-optic front sight with a low-profile dovetail rear. Hogue black rubber boot-style grips are standard. It is DAO with a shrouded hammer. 


When it comes to supportability, it uses K6 speed loaders and J-frame grips. The MSRP on the new Diamondback SDR-A is $614, which is a good bit lower than the company's all-steel revolvers, which start at $777. 

You can be sure we will bring you more on these from SHOT Show later this month.
