The Smith & Wesson Model 66 Combat Magnum is a medium-frame K-Frame revolver chambered in .357 Mag. Its 2.75-inch stainless steel barrel and six-shot stainless steel cylinder provide a practical balance of portability and full-power revolver capability. The exposed hammer supports both single-action and double-action fire, while the red-ramp front sight and adjustable white-outline rear sight provide a clear, serviceable aiming setup. A full top strap, barrel serration, ball-detent lock-up, and two-piece barrel reflect the Model 66's established K-Frame design.
