Function and installation
The main spring provides the force needed for reliable hammer operation and ignition. A worn or incorrectly matched spring can affect trigger pull, hammer performance, and reliable firing.
This is a used fire-control component. Inspect it for wear, deformation, and correct tension before installation. Professional gunsmith installation is recommended because revolver disassembly and spring replacement can affect safe operation.
This listing is for the main spring only. No firearm, frame, or other revolver parts are included.
