Diamondback SDR Features The Diamondback SDR operates in double action or single action giving shooters a smooth deliberate trigger pull for precision or a fast trigger stroke for quick follow-up shots under stress. Fixed fiber optic sights an orange front and green rear gather ambient light for a fast sight picture in low light a real advantage over plain black sights in a defensive scenario. Chamfered cylinder chambers and an ergonomically placed push-button cylinder release let the shooter reload smoothly under pressure without fumbling for a stiff latch. A 6-groove rifled barrel and a non-stacking trigger help deliver consistent accuracy shot after shot. Machined entirely from forged stainless steel and finished in a durable Black Nitride+ coating the SDR s frame cylinder and barrel resist corrosion and holster wear far better than a standard blued gun carried daily. Black Hogue rubber grips stamped with the Diamondback logo give a secure comfortable hold that helps manage recoil in both .357 Magnum and .38 Special +P loads. At 6.53 inches overall and 21.2 ounces the SDR strikes a practical balance between concealability and the recoil-taming heft of an all-steel build. The Diamondback SDR is a well-rounded choice for concealed carry shooters and home defenders who want a rugged dual-caliber revolver.
