The Diamondback Firearms SDR is a compact 9mm double-action revolver with a stainless steel frame and a 2-inch barrel. It holds six rounds in the cylinder and weighs 21 ounces, with an overall length of 6.7 inches. The rubber grip and low-profile fiber optic sights complete a small, streamlined package with no external safeties.

A revolver with this profile suits concealed carry and personal defense, where a small, simple handgun is the goal. The rounded edges and concealed hardware are there to limit snags on the draw. The chambers are chamfered to work with TK Custom moon clips, which speed up loading and extraction for a shooter who uses them. Buying it works like any other handgun: a dealer, Form 4473 and a background check, with state permits or waits where they apply.
