Wilson Combat Spring Kit for S&W K/L/N Frame Revolvers – Complete Action Tune

The Wilson Combat Spring Kit for S&W K/L/N Frame revolvers replaces factory springs to smooth trigger pull and reduce weight while maintaining reliable ignition. Designed for Smith & Wesson double-action revolvers, this kit addresses the most common trigger complaints—heavy, gritty pull and stacking—without compromising function or safety. Wilson Combat's springs are precision-manufactured from high-grade steel for consistent performance across thousands of cycles.

This kit is compatible with Smith & Wesson K-frame (medium), L-frame (medium-large), and N-frame (large) revolvers including models like the 10, 19, 64, 66, 586, 686, 27, 29, and 625. Kit includes mainspring, rebound spring, and trigger return spring. Installation requires basic gunsmithing tools and disassembly knowledge. Professional installation recommended if unfamiliar with revolver internals. Always function-check with your chosen carry ammunition after installation.
