The RM66 features Rossi’s prized double action trigger and an unbelievably crisp single action trigger pull. To allow you to take the best advantage of those triggers the RM66’s six-inch barrel pairs with a red ramp front sight and a fully adjustable rear sight. This allows you to zero the RM66 for your ammo of choice whether it’s 158 grain .357 Magnum or 130 grain .38 Special.
The RM66 has 6 shots of .357 Magnum on tap in its steel cylinder. The full underlug barrel adds additional weight which helps manage magnum recoil. Further aiding recoil reduction is the wrap-around rubber grip cushioning your hand during firing. There are already a considerable number of accessories available for the RM66 as it fits common holsters and speed loaders for similar sized medium frame revolvers.
