Frequently Asked Questions

What are the main advantages of the new Diamondback SDR-A revolver?

The Diamondback SDR-A's primary advantages are its significantly reduced weight due to the aluminum frame and shroud, making it easier to carry. It also maintains an affordable price point, offering a budget-friendly option in the lightweight revolver market.

What are the biggest criticisms of the Diamondback SDR-A?

The most significant criticisms are the downgrade in caliber from .357 Magnum to .38 Special +P and the conversion to a double-action-only (DAO) mechanism without improving the trigger pull. These changes are seen as compromises that reduce its effectiveness for self-defense.

How does the Diamondback SDR-A compare to competitors like the Kimber K6S?

While the SDR-A is lighter and more affordable, competitors like the Kimber K6S offer more potent .357 Magnum rounds in a similarly lightweight package. The K6S also retains a single-action option, which the SDR-A lacks.

What improvements could make the Diamondback SDR-A a better firearm?

The reviewer suggests that introducing a shrouded hammer would be a major improvement, offering more versatility. Furthermore, returning to .357 Magnum capability, even in the lightweight aluminum frame, would transform it into a highly competitive and desirable firearm.
