Smith & Wesson K Frame Model 15 Barrel Pin Old Style .38 Special — Used OEM Part 151A

Smith & Wesson K Frame Model 15 Barrel Pin Old Style .38 Special — Used OEM Part

Genuine Smith & Wesson OEM barrel pin for the K Frame Model 15 Combat Masterpiece revolver chambered in .38 Special. The barrel pin is the cross-pin that passes through the frame and barrel threads to lock the barrel in place at the correct timing position after installation. On older S&W revolvers, the barrel is threaded into the frame and then pinned — the pin prevents the barrel from rotating out of timing under recoil. A missing or damaged barrel pin allows the barrel to shift over time, causing timing and accuracy issues. This is the old-style barrel pin specific to the Model 15. This used OEM part is inspected and functional, manufactured to original S&W specifications and tolerances.

Condition: Used — inspected and functional. Gunsmith fitting may be required.
