Smith & Wesson J Frame Model 642 Airweight Stirrup Spring & Swivel Stainless .38 Special — Used OEM Part 642141A
Smith & Wesson J Frame Model 642 Airweight Stirrup Spring & Swivel Stainless .38 Special — Used OEM Part
Genuine Smith & Wesson OEM stirrup spring and swivel for the J Frame Model 642 Airweight revolver chambered in .38 Special. The stirrup spring and swivel are components of the hammer stirrup assembly — the linkage that connects the trigger to the hammer in the double-action mechanism. The spring provides the return tension that resets the stirrup after each trigger pull, while the swivel allows the stirrup to pivot as the trigger and hammer cycle. A worn or broken stirrup spring causes inconsistent trigger pull weight or failure to reset in double-action mode. Stainless steel construction to match the Model 642's original configuration. This used OEM set is removed from a used firearm and in good working condition, manufactured to original S&W specifications and tolerances.
Condition: Used — inspected and functional. Some fitting by a qualified gunsmith may be necessary.

Finding Your Model Number
Swing out the cylinder and look behind the yoke on the frame. Model numbers were added starting in 1957–58. If your revolver has no model number stamped, it may be a pre-model variant — verify compatibility before ordering.
