S&W 17-4 K-22 Masterpiece .22 LR Revolver

The Rimfire Precision Standard: The K-22 Target Legacy 

The Smith & Wesson Model 17-4, serial 21K5951, is a classic representative of S&W's premium rimfire target line. The "-4" engineering dash code coupled with the "21K" serial prefix places its manufacture in the late 1970s. This era represents the final chapter of the traditional pinned-barrel configuration for the K-frame target family. Originally introduced as the K-22 Masterpiece, the Model 17 was engineered to match the exact weight, balance, and sight picture of its centerfire siblings, the Model 14 (.38 Special) and Model 19 (.357 Magnum). This allowed target shooters and law enforcement officers to conduct high-volume, low-cost training with identical physical mechanics. This specific specimen features the elongated, factory 8.375-inch target barrel, designed to extract maximum velocity and an extended sight radius for competitive silhouette and bullseye target shooting.

Condition and Action Highlights

Action: Double-Action / Single-Action (DA/SA) target operating system. The internal lockwork functions smoothly and is perfectly in time.

Condition: Excellent condition. The deep factory high-polish blued finish is remarkably well-preserved across the frame, cylinder, and the long 8.375-inch barrel. High-edge holster wear and muzzle thinning are completely absent. The only visible cosmetic characteristic is a faint, superficial cylinder turn-line that has not cut through the blue finish.

Grips & Hardware: Fitted with its original OEM checkered walnut target stocks featuring inlaid silver S&W medallions. The checkering is sharp, and the wood panels are free of chips, deep scratches, or edge compression. The target hammer and target trigger retain vivid, high-contrast factory color-case hardening.

Bore & Cylinders: 8.375-inch barrel; the internal bore is clean and bright with sharp factory rifling. The six individual chamber mouths are crisp and completely free of rim-damage from dry firing.

Packaging: Includes its original factory blue cardboard box with matching label information.
