Built on the stainless K-Frame, the Model 66-8 combines a durable matte stainless finish on the frame, cylinder, and receiver with a classic six-shot fluted cylinder. The partial underlug protects the ejector rod while leaving the knurled tip exposed, and the revolver operates in double-action/single-action with a smooth-face trigger and an exposed hammer with a checkered spur.
The 4.25 inch barrel uses a two-piece, tensioned design and carries the .357 MAGNUM / COMBAT MAGNUM rollmarks. A ball-detent front yoke lock supports solid lockup, and the internal key lock is incorporated into the frame.
Sight regulation is handled by a pinned red/orange ramp front sight paired with an adjustable target-style rear, providing a clear, traditional iron-sight picture suitable for precise elevation and windage adjustments.
The black wraparound synthetic grip with pebble texturing offers a secure, comfortable hold. Overall length is approximately 9.69 inches, and weight is about 36.6 ounces. This United States–made revolver corresponds to S&W part number 162662 and is designated within the Combat Magnum series.
