The Smith & Wesson models 586 / 686 fulfil the desire of CO2 shooters requiring a revolver. Corresponding to the legendary 357 Magnum revolver both in handling and weight, the S&W CO2 revolver offers the choice of three barrel lengths. This new pistol has a very nice feel to it. It has a full metal construction except the grips which are a solid rubber for comfort. This has a removeable barrel to interchange with other lengths (not supplied) and for cleaning.
