Smith & Wesson K Frame Model 10-7 4" Tapered Pinned Barrel — Blue Steel — Part# 1021A

Used OEM factory 4" tapered pinned barrel for the Smith & Wesson K Frame Model 10-7 revolver in .38 Special. The tapered pinned barrel was used on S&W revolvers through the Model 10-7 era — the barrel pin locks the barrel to the frame for precise alignment and consistent accuracy, while the tapered profile reduces weight toward the muzzle for improved balance. A direct factory replacement for period-correct restoration.

How to Identify Your S&W Model Number

Swing out the cylinder and check behind the yoke on the frame. Model numbers were introduced in 1957–58. If no model number is present, your revolver may pre-date that era — contact us with your serial number and we can help identify the correct part.

Installation

Barrel installation requires proper headspacing and timing verification. Installation by a qualified gunsmith is strongly recommended.
