Smith & Wesson J Frame Model 30 Stirrup Spring Swivel - Used
This listing is for a used Smith & Wesson J Frame Model 30 stirrup spring swivel. Factory OEM part sold as-is.
The stirrup spring swivel is a small but critical component of the J Frame cylinder latch assembly, working in conjunction with the stirrup and thumbpiece to allow the cylinder to swing out for loading and unloading. This used factory part is correct for the Model 30 — S&W's classic .32 S&W Long Hand Ejector — and is an essential find for gunsmiths restoring or servicing this vintage revolver.

Note: The Model 30 is chambered in .32 S&W Long, a distinct cartridge from .38 Special. Small parts like the stirrup spring swivel may share fitment across some J Frame models of the same era, but always confirm your specific model and dash number before ordering. To find your model number, swing out the cylinder and check behind the yoke on the frame. Models without a number predate 1957–58 — contact us with your serial number for assistance.
