Detailed Features 

The 4-inch barrel gives the RM64 a usable sight radius for accurate DA or SA fire at practical ranges. Dual-caliber capability (.357 Mag and .38 Special) lets shooters use cheaper .38 Special for practice and carry .357 Mag loads for defense or hunting. The matte stainless finish is practical for outdoor use, no polishing needed and corrosion-resistant. Adjustable rear sight and serrated front sight.

The RM64 is frequently recommended as a budget-accessible entry point for the .357 Magnum revolver category. Price is the dominant theme in positive feedback. Owners consistently note that the Rossi delivers reliable revolver mechanics at a price below competing options from S&W or Ruger.

The matte stainless finish gets consistent praise for durability and practicality. The DA/SA trigger is generally well-regarded. The double-action pull is smooth enough for practical shooting and the single-action break is clean. Dual .357 Mag and .38 Special compatibility is mentioned regularly as a practical advantage.

Quality control is the main critical theme. A meaningful minority of buyers report fit and finish issues or mechanical problems requiring attention before the gun ran smoothly out of the box. This is the most consistent complaint and comes up often enough that buyers are routinely advised in online communities to carefully inspect each individual example. Six-round capacity is sometimes noted as a limitation versus semi-autos, though this is inherent to the revolver platform. Some buyers find the rubber grip adequate, others prefer aftermarket options for better ergonomics. Experienced reviewers typically describe it as a good value for buyers who inspect carefully rather than an unconditional recommendation.
