Frequently Asked Questions

What are the main pros of the Diamondback SDR revolver?

The Diamondback SDR is praised for its J-frame size, making it concealable, and its six-shot capacity in .357 Magnum. It features a unique captured cylinder system, good ergonomics, and a snag-free bobbed hammer on the Taylor Edition, making it aesthetically pleasing and comfortable to carry.

What are the significant cons of the Diamondback SDR?

The primary issues include lead spitting from an uneven and oversized cylinder gap, causing injury. Additionally, the firearm consistently shoots high, and shell casings can stick during ejection. Holster compatibility is also a challenge due to its slightly different frame dimensions compared to standard J-frames.

How does the Diamondback SDR handle recoil?

Recoil with .357 Magnum is described as stout for its 21-ounce weight, more so than a slightly heavier S&W 640. However, it handles .38 Special and .38+P ammunition very softly and is considered extremely tame for all-day shooting.

Is the Diamondback SDR suitable for concealed carry?

On paper, it's a strong candidate due to its size and capacity. However, the reported issues with lead spitting, accuracy, ejection, and limited holster availability present significant drawbacks that potential buyers should consider before relying on it for concealed carry.
