S&W K Frame Model K38 Pre-Model 15 Barrel Pin .38 Special – Part# 15002

Smith & Wesson K Frame Model K38 Pre-Model 15 Barrel Pin – Old Style

Replace a worn or missing barrel pin on your K38 or Pre-Model 15 with this factory-original component. The barrel pin (also called the barrel retaining pin) passes through the frame and barrel shank to lock the barrel in its threaded position, preventing it from rotating under recoil — a missing or damaged pin allows the barrel to unscrew over time, affecting accuracy and potentially creating a safety hazard. This old-style blue steel pin features the correct 5-screw era design for the K Frame Model K38 (Pre-Model 15) chambered in .38 Special.

About the K38 / Pre-Model 15

The K38 Masterpiece (later designated the Model 15 Combat Masterpiece) is one of the most celebrated K Frame revolvers ever produced. Pre-model revolvers predate the 1957–58 model number system; if your revolver has no model number stamped behind the yoke, contact us with the serial number and we'll confirm compatibility.
