Diamondback S.D.R. .357 Magnum Revolver, 2-Inch Barrel, 6-Round, Stainless Steel, SA/DA

The Diamondback S.D.R. .357 Magnum revolver is a compact, purpose-built defensive handgun that doesn't compromise on reliability or shootability in a small package. Built from forged stainless steel and weighing just over 21 ounces, this 2-inch barrel revolver is engineered for concealed carry without sacrificing the stopping power of full-power .357 Magnum loads or the affordability of .38 Special practice rounds. If you're looking for a dependable revolver that handles both duty and deep concealment equally well, the S.D.R. delivers.

The revolver's compact footprint—just 6.5 inches overall—makes it comfortable to carry inside the waistband or in a jacket pocket, while its polished stainless finish resists corrosion in all weather. Low-profile fiber-optic sights (orange front, green rear) provide fast target acquisition in varied lighting, and the rounded edges and concealed hardware eliminate snag points during the draw. The ergonomic push-button cylinder release and chamfered chambers make reloading intuitive under stress, whether at the range or when it counts.

The DA/SA action gives you flexibility: double-action for a longer, more controlled first shot, or cock the hammer for single-action precision on follow-ups. The trigger breaks clean at 9–11.5 pounds with no stacking, promoting accuracy without requiring a break-in period. The 6-round capacity trades magazine capacity for a truly pocketable gun—exactly what defensive revolver users expect.

Diamondback's attention to match-grade trigger quality and quality control makes the S.D.R. a genuine alternative to more expensive EDC revolvers, without the marketing premium. This is a gun built to work, not to impress.
