Diamondback Introduces the SDR-A

Lightweight, Hammerless Aluminum Revolver Built For Everyday Carry

‍

Cocoa, FL – January 9th, 2026 – Diamondback Firearms announces the launch of the SDR-A, an aluminum-frame, hammerless .38Special +P revolver engineered specifically for modern everyday carry. The SDR-A expands Diamondback’s Small Defensive Revolver lineup with a lightweight, snag-free option designed for personal protection, concealability, and reliability.

Built on a forged 7075-T6 aluminum frame and weighing just 15.6 ounces, the SDR-A is Diamondback’s lightest revolver to date. Chambered in .38 Special +P SDR-A is purpose-built for defensive carry without sacrificing performance or durability.

The hammerless design eliminates snag points during draw while maintaining a smooth, non-stacking double-action trigger pull rated between 9.0 and 11.5 pounds, optimized for safe, consistent EDC use. A fixed orange fiber-optic front sight paired with a low-profile green fiber-optic rear sight enhances rapid target acquisition in defensive scenarios.

“Modern shooters are rediscovering revolvers for everyday carry, and the demand for lightweight, American-made options continues to grow,” said Simon McCartney, Sales and Business Development Manager at Diamondback Firearms. “The SDR-A supports that demand by delivering a revolver that is easy to carry, simple to operate, and built with the quality today’s customers expect.”

The SDR-A features a 2-inch stainless steel barrel, a stainless steel cylinder, and Diamondback’s proven push-button cylinder release for fast, intuitive operation. A Hogue rubber grip with Diamondback branding enhances control while maintaining compatibility with J-frame-style grip options, giving users flexibility with aftermarket accessories and carry preferences.

“The SDR-A was designed with real-world personal protection in mind,” said Dave Larson, Marketing Director at Diamondback Firearms. “Its aluminum frame dramatically reduces carry weight, and the hammerless design makes it ideal for concealed carry without compromise. This is a revolver you can comfortably carry every day, not just own.”

As part of Diamondback’s continued commitment to American manufacturing, the SDR-A is proudly made in the USA and expands a revolver lineup that now spans stainless steel, nitride, polished, and lightweight aluminum configurations.
