Key Features
Construction & Durability
The Diamondback SDR revolver features a robust stainless steel frame, cylinder, and a 3-inch stainless steel barrel. This material selection ensures inherent corrosion resistance and structural integrity, contributing to the revolver’s extended service life and consistent performance under demanding conditions. The precision-machined components facilitate reliable operation and durability, a critical factor for any duty or defense application.
Operational Functionality
Engineered with a Single Action/Double Action (SA/DA) mechanism, the SDR provides operational versatility. The exposed hammer allows for manual cocking, enabling a lighter, more precise single-action trigger pull for targeted engagements. The double-action mode offers a consistent, heavier pull for rapid response. The trigger pull is calibrated within a 9 lbs to 11.50 lbs range, providing a predictable operational interface.
Sighting System
The SDR integrates a high-visibility sighting system to optimize target acquisition. The front sight is a fixed fiber optic orange, effectively drawing the eye. This is complemented by a low-profile dovetail fiber optic green rear sight, providing a clear and rapid sight picture across varying light conditions, enhancing practical accuracy.
Ergonomics
A black Hogue rubber grip, prominently featuring the Diamondback logo, is standard. This grip material and ergonomic design are specifically selected to mitigate felt recoil and ensure a secure, comfortable interface for the shooter. This enhances control during sustained firing sequences and contributes to overall operational efficiency.
