Also known as: K-22 MRF Masterpiece

Overview

The Smith & Wesson Model 48 is a medium revolver built on Smith & Wesson's K-frame, introduced in 1959. Chambered in .22 Winchester Magnum Rimfire with a 6-round cylinder. Built with a steel frame, this revolver continues Smith & Wesson's tradition of robust, reliable revolver construction. The 4.0-inch barrel provides an excellent balance of sight radius and portability, suitable for both duty carry and range work. At 1076g (38.0 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.
