This Model 66-8 features a two-piece barrel with a partial underlug and a shrouded ejector rod, providing a balanced profile while protecting critical components. The serrated top strap helps cut glare, and the barrel flats are roll-marked "SMITH & WESSON" and ".357 MAGNUM" / "COMBAT MAGNUM."
The sighting system is straightforward and effective: a red-ramp front sight pairs with an adjustable white-outline rear, both set up for precise iron-sight shooting. The action is DA/SA with a smooth, combat-style trigger and an exposed, checkered-spur hammer for confident control.
Construction is all-stainless, including the matte stainless frame and receiver and a matching fluted stainless cylinder. A ball-detent/yoke-detent lock-up enhances cylinder alignment and consistency. The revolver is a 6-shot K-frame that accepts .357 Magnum and .38 Special, including +P.
Ergonomics include a black synthetic one-piece grip with finger grooves and S&W medallions. Overall length is about 9.69 inches with an approximate weight of 36.9 ounces, delivering a full-size feel and steady handling. Safety features include an internal key lock. Markings include "MADE IN U.S.A. MARCAS REGISTRADAS SMITH & WESSON SPRINGFIELD, MA." and the S&W trademark logo on the right frame.
