Smith & Wesson J Frame Pre-Model 36 Chief's Special Main Spring & Stirrup .38 Special — Used (Part# J3642)
This listing is for one used Smith & Wesson J Frame Pre-Model 36 (Chief's Special) main spring and stirrup assembly chambered in .38 Special. This is an OEM factory part in used condition, removed from a functioning firearm. The main spring (hammer spring) powers the hammer, and the stirrup links the spring to the hammer — both are critical to reliable double- and single-action operation.
⚠️ Professional installation recommended. Disassembly and reassembly of the firearm is required to replace this part. Some parts may require fitting by a qualified gunsmith.
