The Smith & Wesson (S & W) Model 686, is a six- or seven-shot double-action revolver chambered for the .357 Magnum cartridge. It will chamber and fire .38 Special cartridges, as the .357 Magnum was developed from the .38 Special. The magnum case is slightly longer to prevent magnum rounds from being chambered and fired in handguns chambered for the .38 Special. The 686 has been available with 2-1/2 in. (64 mm); 3 in.(76mm); 4 in. (102 mm); 5 in. (127 mm); 6 in. (153 mm); and 8-3/8 in. (214 mm) barrel lengths as standard models and other barrel lengths either by special order from S & W's Performance Center custom shop, or acquired from or built by after-market gunsmiths. The Performance Center made a limited number of 686 in .38 Super for competitive shooters.〔 Smith & Wesson introduced the Model 686 in 1980. It is the stainless steel version of the 586, which was a blued steel finish. It was chambered for .357 Magnum and .38 S&W Special +P calibers. They are available ported and unported with a choice of 6 or 7 round cylinders.〔 The Model 686 is based on S & W's K/L (medium-large) revolver frame. During the 1980s, Smith & Wesson developed its K/L-Frame line of .357 Magnums: the Model 581, Model 586, Model 681 and Model 686. The Models 581 and 681 have fixed sights, whereas the 586 and 686 use adjustable sights. ==Variants of the 686== * S&W Model 686 (US - Revolver - .357 Magnum & .38 Special: Distinguished Combat Magnum 6-shot cylinder, Stainless) * S&W Model 686P (US - Revolver - .357 Magnum & .38 Special: Distinguished Combat Magnum 7-shot cylinder, Stainless) * S&W Model 686PP (US - Revolver - .357 Magnum & .38 Special: Distinguished Combat Magnum Power Port 6-shot cylinder, Stainless) The Model 686 has an adjustable rear sight, and until 1992, the 6- and 8-3/8-inch versions had the option of an adjustable front sight.
