This small but critical spring sits behind the elevation and windage plunger\/detent ball in the rear sight body, providing the tension that creates the crisp, positive clicks you feel when adjusting your sight. A worn or broken spring results in mushy, inconsistent adjustments that won't hold zero — replacing it restores the precise, repeatable sight movement your revolver was designed to deliver.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 036390000\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 Rear Sight Plunger\/Detent Spring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Spring steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Compatibility:\u003c\/strong\u003e K, L, N, X Frame — all models with adjustable rear sights\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Tensions the elevation and windage plunger\/detent ball; creates positive adjustment clicks\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\u003eCompatible Frame Families\u003c\/h3\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"border-bottom:2px solid #ddd;\"\u003e\n\u003cth style=\"text-align:left; padding:8px;\"\u003eFrame\u003c\/th\u003e\n\u003cth style=\"text-align:left; padding:8px;\"\u003eExample Models\u003c\/th\u003e\n\u003cth style=\"text-align:left; padding:8px;\"\u003eCompatibility\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"border-bottom:1px solid #eee;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eK Frame\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e14, 15, 16, 17, 18, 19, 48, 53, 66, 67, 617\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e✓ Compatible — all adjustable sight variants\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"border-bottom:1px solid #eee;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eL Frame\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e581, 586, 681, 686\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e✓ Compatible — all adjustable sight variants\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"border-bottom:1px solid #eee;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eN Frame\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e24, 25, 27, 28, 29, 57, 58, 624, 625, 627, 628, 629, 657\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e✓ Compatible — all adjustable sight variants\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"border-bottom:1px solid #eee;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eX Frame\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e460, 500\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e✓ Compatible — all adjustable sight variants\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"border-bottom:1px solid #eee;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eJ Frame\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eAll models\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e✗ Not compatible — different rear sight assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eComplete Your Rear Sight\u003c\/h3\u003e\n\u003cp\u003eThis spring works in conjunction with the plunger\/detent ball and the rear sight body.
