Also known as: Combat Magnum Stainless

Overview

The Smith & Wesson Model 66 is a medium revolver built on Smith & Wesson's K-frame, introduced in 1970. Chambered in .357 Magnum with a 6-round cylinder. Constructed with a stainless steel frame and cylinder, this revolver offers excellent corrosion resistance and durability for years of reliable service. The 4.3-inch barrel provides an excellent balance of sight radius and portability, suitable for both duty carry and range work. At 1046g (36.9 oz), this is a substantial revolver that uses its mass to tame recoil from powerful magnum loads, making extended range sessions more comfortable. Smith & Wesson has been producing K-frame revolvers for well over a century, continuously refining the platform with improved metallurgy, ergonomics, and manufacturing techniques while maintaining the fundamental reliability and accuracy that has made their double-action revolvers the benchmark against which all others are measured.
