Wilson Combat Spring Kit for S&W J Frame Revolvers – Enhanced Trigger Action

The Wilson Combat Spring Kit for S&W J Frame revolvers replaces factory springs to deliver a smoother, more consistent trigger pull in both double-action and single-action modes. Designed for small-frame Smith & Wesson revolvers, this kit reduces trigger stack and creep while maintaining reliable ignition with all standard primers. Wilson Combat engineers these springs to strict tolerances for durability and performance across thousands of rounds.

Compatible with S&W J Frame models including the 442, 642, 638, and similar small-frame revolvers. Kit includes mainspring, rebound spring, and trigger return spring. Installation requires basic gunsmithing tools and knowledge of revolver lockwork. Test function with your carry ammunition after installation to ensure reliable ignition.
