The Model 48 K-22 Masterpiece MRF chambers the .22 Winchester Magnum Rimfire on the K-frame with a 6-inch barrel and full adjustable target sights. Designed for small-game hunters and target shooters who wanted more power than .22 LR from a K-22-type revolver, it was made in relatively small numbers compared to the .22 LR Model 17. Original examples are scarce.
