Smith & Wesson N Frame Model 57 Mainspring – .41 Magnum (Old Style, Used)
Restore reliable hammer fall on your Model 57 with this genuine Smith & Wesson factory mainspring. Also called the hammer spring, the mainspring drives the hammer forward to fire the cartridge — a weak or broken mainspring causes light primer strikes, misfires, or a heavy, inconsistent trigger pull. A common replacement during action work or revolver restoration.
Old-style configuration correct for the Model 57. Sourced from a used firearm and inspected for function.

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.
