The Model 66-8 is marked on the yoke cut and built on a stainless K-frame with a round-butt grip frame. The barrel is marked ".357 MAGNUM – COMBAT MAGNUM." The 2.75 inch two-piece barrel uses a partial underlug for balanced carry while retaining duty-ready durability.
Sight regulation is straightforward with a pinned red/orange-insert ramp front and a fully adjustable rear. A serrated topstrap helps reduce glare along the sighting plane. The knurled ejector rod and ball-detent crane lock contribute to positive operation and consistent cylinder alignment.
This revolver uses a frame-mounted firing pin and includes an internal key lock safety. The 6-shot cylinder is fluted and finished to match the satin stainless frame and barrel. The installed grips are custom checkered, finger-grooved wood stocks with S&W medallions and scrollwork; two factory S&W-logo rubber grips—one one-piece wraparound finger-groove and one two-panel service-style with cross-bolt screw—are also included.
Factory identifiers align with SKU/Mfg Part Number 10061, and the case end label reflects the 2.75 inch barrel and .357 Magnum chambering. This United States–made Combat Magnum presents as a compact, carryable K-frame with modern production updates and classic S&W cues.
