Diamondback SDR Features The Diamondback SDR is built around a forged stainless steel frame and 2 stainless steel barrel machined to tight tolerances and finished in a polished stainless treatment for superior corrosion resistance and a refined appearance suited to both carry and display. The DA/SA action delivers a trigger pull weight of 9 to 11.5 lbs in double-action for reliable defensive deployment while the exposed hammer allows single-action operation for deliberate precision shots when the situation allows. An exceptionally smooth trigger pull chamfered cylinder chambers and ergonomically placed push-button cylinder release ensure fast reliable loading and ejection under defensive conditions. The Diamondback SDR features a fixed orange fiber optic front sight and low-profile dovetail green fiber optic rear sight for fast intuitive target acquisition in varied lighting conditions suited to close-range self-defense engagements. Rounded edges throughout eliminate snag points on clothing and holsters for a clean consistent draw from concealment. A black Hogue rubber grip with Diamondback logo provides a secure comfortable hold that manages the 9mm s recoil impulse through rapid defensive strings of fire. The SDR s compact small-frame profile 1.38 width and 4.44 height position it as an ideal home and personal defense revolver for shooters who prefer the simplicity and reliability of a revolver in a 9mm chambering compatible with commonly available defensive ammunition. The alloy steel cylinder and six-groove barrel rifling contribute to consistent ballistic performance across standard and +P 9mm defensive loads. Polished stainless construction on the frame barrel and cylinder creates a cohesive low-maintenance finish package suited to the demands of daily carry.
