The Diamondback Firearms Sidekick revolver integrates a flexible rimfire platform designed for diverse operational requirements. Chambered primarily in .22LR, this revolver includes an additional .22WMR cylinder, facilitating a direct transition between economical ammunition for high-volume practice and a more potent cartridge for enhanced terminal performance. This dual-caliber capability effectively supports activities ranging from target acquisition and competitive shooting practice to varmint control and small game hunting.
Key Features
Caliber Versatility
The Sidekick ships equipped with two 9-round cylinders: one specifically machined for .22LR and another for .22WMR. This design allows the operator to quickly and efficiently change calibers based on immediate application or cost-efficiency requirements, optimizing utility for both training and field use.
Action Type
Operating in both single-action and double-action modes, the Sidekick offers the user control over trigger pull characteristics. This provides adaptability for precise, deliberate single-action shots or quicker, double-action engagements, depending on user preference and situational demands.
Barrel Configuration
Featuring a 5.5-inch silver finish barrel, this configuration contributes to a consistent sight radius, which is critical for precise shot placement. The barrel length is engineered to balance maneuverability with ballistic performance for rimfire cartridges.
Robust Construction
Constructed with a durable zinc frame, the Sidekick utilizes steel for its barrel and cylinders. This material combination ensures operational reliability and longevity under varied conditions, providing a stable platform for consistent performance.
Ergonomic Grip
The revolver is equipped with a bird’s head style polymer grip. This ergonomic design is engineered to provide a secure and comfortable hold, mitigating felt recoil and facilitating positive control during sustained firing sessions.
