The Rossi RM66 .357 Magnum revolver is engineered for consistent performance and durability, suitable for both range applications and duty considerations. This platform integrates proven revolver mechanics with essential features for repeatable accuracy and robust operation.
Key Features
Caliber and Capacity
Chambered in .357 Magnum, the RM66 provides significant ballistic energy while maintaining compatibility with .38 Special ammunition for training or reduced recoil applications. Its 6-round cylinder capacity delivers an appropriate round count for a service-oriented revolver.
Barrel Configuration
The 6-inch barrel length is a critical component for optimizing ballistic performance, contributing to increased muzzle velocity and an extended sight radius. This longer sight radius facilitates more precise shot placement, a key factor for shooters prioritizing accuracy.
Sighting System
Equipped with adjustable sights, the RM66 allows for precise zeroing and user-defined sight picture optimization across varying ammunition types or distances. This adaptability enhances the shooter’s ability to achieve consistent point of impact.
Construction and Finish
Constructed from durable steel with a blued finish, the RM66 chassis is designed to withstand rigorous use. The material selection and surface treatment contribute to the firearm’s operational longevity and resistance to environmental factors.
Ergonomics
The revolver features a grip designed to provide a secure and consistent hold, mitigating felt recoil and promoting enhanced control during rapid fire sequences or extended range sessions.
