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. The tapered profile reduces weight toward the muzzle for improved balance. This used OEM barrel is a direct factory replacement for period-correct restoration of Model 10-7 revolvers.

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

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.
