The mainspring provides the tension that drives the hammer forward to strike the firing pin. In a DA\/SA pistol like the CS9 series, the mainspring must deliver consistent tension for both the long double-action first pull and the shorter single-action follow-up shots. A weak, fatigued, or broken mainspring causes light primer strikes, failure to fire, or inconsistent ignition. Replacing it with a genuine OEM spring restores proper hammer tension and reliable function.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 263200000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Smith \u0026amp; Wesson\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Mainspring (Hammer Spring)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 9mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAction:\u003c\/strong\u003e DA\/SA (Double Action \/ Single Action)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Factory New — genuine OEM part\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eSmith \u0026amp; Wesson CS9 Chief's Special (9mm) — 3rd Generation Compact\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSmith \u0026amp; Wesson CS9C Chief's Special Compact (9mm) — 3rd Generation Compact\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSmith \u0026amp; Wesson CS9S Chief's Special (9mm) — 3rd Generation Compact\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Verify your specific model variant before ordering.\u003c\/p\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThis listing is for the mainspring only.\u003c\/strong\u003e The mainspring cap, strut, and all other action parts are sold separately.\u003c\/li\u003e\n\u003cli\u003eDisassembly of the action is required for installation.\u003c\/li\u003e\n\u003cli\u003eGunsmith installation recommended.
