Diamondback Firearms has introduced the SDR-A Black as an addition to its lightweight SDR-A revolver series. The six-shot .38 Special +P model features a forged 7075-T6 aluminum frame with black anodized finish, a black nitride stainless-steel cylinder, a black PX5-finished stainless-steel barrel shroud, a 2-inch stainless-steel barrel, orange fiber-optic front sight, and low-profile dovetail green fiber-optic rear sight. The hammerless double-action-only design weighs 15.6 ounces, measures 6.70 inches overall, uses a Hogue black rubber grip with the company logo, and has a 9.0- to 11.5-pound trigger. Unlike the stainless-steel SDR, which is offered in .357 Magnum/.38 Special +P or 9mm with hammer variants, the SDR-A Black is chambered only in .38 Special +P.
