A fatigued or broken mainspring causes light strikes, misfires, or a heavy, inconsistent trigger pull. This is a genuine S\u0026amp;W factory old-style stainless steel mainspring pulled from a Model 686 and ready to restore reliable ignition.\u003c\/p\u003e\u003ch3\u003ePart Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 6869\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Used (Old Style)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Smith \u0026amp; Wesson L Frame Model 686 (.357 Magnum)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM:\u003c\/strong\u003e Smith \u0026amp; Wesson factory part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eThis part fits the S\u0026amp;W L Frame Model 686.
