Smith & Wesson L Frame Model 686 Mainspring .357 Magnum - Part# 6869

Smith & Wesson L Frame Model 686 Mainspring

Part# 6869 | .357 Magnum | Stainless Steel | Old Style Used Part

The mainspring (also called the hammer spring) is the powerplant of your S&W revolver's action — it drives the hammer forward with enough force to reliably detonate primers in both single- and double-action fire. A fatigued or broken mainspring causes light strikes, misfires, or a heavy, inconsistent trigger pull. This is a genuine S&W factory old-style stainless steel mainspring pulled from a Model 686 and ready to restore reliable ignition.
