The RM66 features Rossi's double action trigger and a crisp single action trigger pull. The RM66s 6"-barrel pairs with a red ramp front sight and a fully adjustable rear sight. 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.
