The Smith & Wesson K-22 M.R.F. Masterpiece Revolver (Model 48) is a six-shot, double-action revolver with adjustable open sights, built on the medium-size "K" frame. It is chambered for the .22 Winchester Magnum Rimfire cartridge, which was also introduced in 1959. [1]
The Model 48 is based off of the Smith & Wesson K-22 Target Masterpiece revolver (also known as the Model 17) chambered in .22 long rifle (the most notable difference is a .224-inch broach through the barrel instead of a .222-inch one used in .22 LR) cartridges. Most K-22 revolvers were fitted with a 4 in (100 mm), a 6 in (150 mm) or 8+3⁄8 in (210 mm) barrel, but other lengths have been produced. [2] [3]
First produced in 1959 as the K-22 M.R.F. Masterpiece, it was numbered the Model 48 in 1959 when all Smith & Wesson guns were given numerical model numbers. It is built on the same frame as the seminal Smith & Wesson Model 10 ("Military and Police") revolver.

The Smith & Wesson Model 648 is a double-action revolver that is chambered in .22 Winchester Magnum Rimfire. Released with a 6-round (later an 8-round) cylinder, it replaced the Model 48 (which as discontinued in 1986) in 1989. The Model 648 was discontinued by 1996, but was reintroduced in 2003; it was soon discontinued in 2005. Even though the Model 48 was reintroduced in 2010 as one of the “Classic” lines, the Model 648 was reintroduced in 2019. [4] [5] [6]
The Model 48 was discontinued in 1986, but in 2010 was reintroduced as the Model 48 "Masterpiece" due to a resurgence in the popularity of vintage Smith & Wesson revolvers. The company chose approximately fifteen previously discontinued models to produce once again. This was done under the "Classics" category of S&W's current offerings. [7]
