Description
Diamondback made some noise when the SDR first hit the market, and for good reason. Most small-frame .357 revolvers give you five shots. This one gives you six, in a frame that still fits the same holsters and hands as a classic snub gun. The DB075AS703 is the Sports South Exclusive version, pairing a 3 inch polished stainless barrel with a Hogue wood grip, and it might be the best looking gun in the SDR lineup. That extra inch of barrel over the standard 2 inch model buys you a longer sight radius and a bit more velocity out of magnum loads, while the added weight up front helps tame recoil without making it a chore to carry.
What Makes the SDR Stand Out
The frame, cylinder, and barrel are all machined from stainless steel, then polished to a finish that looks closer to nickel plating than a typical production gun. The trigger is the real headline though. The double action pull is smooth and non-stacking with no surprise weight at the end, and the single action break off the exposed hammer is short and crisp. For a factory revolver in this class, it is genuinely one of the better triggers you will find out of the box. Fiber optic sights front and rear give you a bright, high-contrast picture that is quick to pick up in low light, and they sit low enough to stay out of the way on the draw.
Living With the Diamondback DB075AS703
Smart details show up all over this gun. The push button cylinder release sits right where your thumb wants it, the chambers are chamfered for faster reloads, and a 45 degree target crown protects the rifling at the muzzle. The grip frame accepts standard J-frame stocks, so swapping grips down the road is easy if the wood ever isn't your style. At 23.9 ounces it carries comfortably all day, and chambered in .357 Mag with .38 Special +P compatibility, you can train soft and carry stout. A good-looking, hard-working six shooter that earns a spot in the rotation.

Frequently Asked Questions
Can the Diamondback SDR shoot .38 Special as well as .357 Magnum?
Yes. Like most .357 Mag revolvers, the SDR handles .38 Special and .38 Special +P without any issue. A lot of owners practice with softer-shooting .38s to keep range sessions comfortable, then load magnums or stout +P rounds for carry. The chamfered chambers also make loading a little quicker either way.
Will other grips fit the SDR if I want to swap out the Hogue wood grip?
The SDR's grip frame accepts standard J-frame style stocks, so you have a huge aftermarket to choose from. That said, the Hogue wood grip on this Sports South Exclusive is a big part of its appeal and feels great in the hand. If you ever want rubber for harder-kicking loads, the swap is simple.
How does the 3 inch SDR compare to the 2 inch version for carry?
The 3 inch barrel adds roughly 2.7 ounces and about an inch of overall length compared to the 2 inch model. In exchange you get a longer sight radius, a little more velocity, and slightly softer felt recoil with magnum loads. It still conceals well in a good belt holster, and many folks find it the sweet spot between shootability and carry comfort.
What is the push button near the trigger guard on the Diamondback SDR for?
That button releases the cylinder and crane assembly as one unit once the cylinder is swung out. Diamondback designed it to make routine cleaning easier, since you can pull the whole cylinder off in seconds without tools. It sits out of the way during normal shooting, so there is no risk of bumping it by accident.
