The Smith & Wesson K-Frame is the backbone of modern revolver collecting. It spans service revolvers, target revolvers, law-enforcement magnums, training guns, and some of the best-known Smith & Wesson model names.
From the Military & Police Model 10 to the .357 Magnum Model 19, the .41 Magnum Model 58, and the K-22 Masterpiece, this family gives collectors a practical way to understand Smith & Wesson history one frame size at a time.
No single Smith & Wesson frame size appears in more collections than the K-Frame. Understanding it unlocks much of Smith & Wesson history.
