Revolvers never really went away, they just stopped caring what anyone thought. While polymer pistols and red dots dominate Instagram feeds, a growing number of shooters are quietly rediscovering the simple brilliance of a good carry revolver. Diamondback Firearms is clearly paying attention, because its newest launch, the SDR-A, is a lightweight, hammerless .38 Special +P revolver built specifically for everyday carry. And not just the “sometimes” kind.
SDR-A Lightweight Where It Counts
The SDR-A expands Diamondback’s Small Defensive Revolver lineup with a forged 7075-T6 aluminum frame that tips the scale at just 15.6 ounces. That’s pocket-friendly, waistband-friendly, and “I forgot this was even on me” friendly. It also makes the SDR-A the lightest revolver Diamondback has produced to date, which is no small feat when durability and shootability still matter.
Chambered in .38 Special +P, the SDR-A sticks to a defensive cartridge that has been getting the job done for decades. No gimmicks, no reinvention, just proven performance in a modernized package.

Built for Concealment
The 2-inch stainless steel barrel and stainless cylinder strike a smart balance between corrosion resistance and recoil management, while keeping the revolver compact enough for serious concealment. The fully enclosed, hammerless design eliminates snag points during the draw. An underrated but critical detail for concealed carry, especially under stress.
This is a double-action-only revolver, featuring a smooth, non-stacking trigger pull rated between 9.0 and 11.5 pounds. It’s heavy enough to be safe for everyday carry without external safeties, but consistent enough to reward shooters who put in range time.

Real Sights & Familiar Controls
Diamondback didn’t phone it in on the sights, either. The SDR-A wears a fixed orange fiber-optic front sight paired with a low-profile green fiber-optic rear. That color contrast makes a noticeable difference in defensive lighting conditions, where traditional gutter-style sights tend to disappear when you need them most.
In short, this isn’t a “point and pray” revolver, it’s one you can actually aim.
Operation is refreshingly straightforward. The SDR-A uses Diamondback’s push-button cylinder release, offering fast, intuitive access without awkward hand gymnastics. The included Hogue rubber grip provides solid control without adding unnecessary bulk and remains compatible with J-frame-style grip options, giving shooters plenty of aftermarket flexibility.

Bottom Line
Diamondback says the SDR-A was designed with real-world personal protection in mind, and the design choices back that up. This isn’t a range toy pretending to be a defensive gun. It’s a purpose-built EDC revolver that prioritizes weight, simplicity, and reliability—three qualities that matter far more than trends when your life might be on the line.
Proudly made in the USA, the SDR-A joins a growing Diamondback revolver lineup that spans stainless, nitride, polished, and lightweight aluminum configurations. With an MSRP of $614, it lands squarely in the competitive defensive revolver market while offering a distinctly Diamondback approach.
