While most known for its AR-15 and AR-10 pattern firearms, Florida manufacturer Diamondback Firearms got its start in 2009 with handguns with the DB380. New for 2024, the company has another unique addition to its line-up of personal protection handguns with the Self-Defense Revolver (SDR).

The SDR is a compact double-action revolver with a swing-out cylinder chambered in .357 Magnum. Despite its compact size, the SDR has a capacity of six rounds, with its chambers chamfered for quicker loading. Opening the action is accomplished with a push-button cylinder release that operates much like the magazine release on a semi-automatic handgun. The cylinder and crane assembly is captured and can be removed from the frame by pushing a release button. Its action is double-action/single-action, with an exposed hammer for cocking in single-action mode. Diamondback calls the trigger “match grade,” and it is engineered for a smooth non-stacking pull and clean break.

Major components of the SDR are made of stainless steel, including the barrel, cylinder and forged frame, which are given a high-polished finish. The 2” barrel has a full underlug that shrouds the ejector rod, and its muzzle is given a 45-degree target crown. With an overall length of 6.53”, height of 4.44” and a cylinder width of 1.38”, the SDR weighs 21.2 ozs. The entire package is contoured and streamlined to save weight and optimize the shape for concealed carry.

While compact revolvers are not known for having good sighting systems, the SDR use a front post with an orange fiber-optic insert that is pinned in place and a rear notch with two contrasting green fiber-optic inserts fitted into a dovetail in the frame’s top strap. Grips are of a “boot” profile and made of rubber with a pebble grain texture and are compatible with a J-frame-type revolver. The SDR will also fit in a holster sized for a J-frame.

The Diamondback Firearms SDR has an MSRP of $777. For more information, visit diamondbackfirearms.com.
