True Precision Recoil Spring Tuning Kit Features The True Precision Recoil Spring Tuning Kit gives Ruger RXM owners six distinct spring weights ranging from 11 lb up to 22 lb so the pistol s cycling can be dialed in for a specific muzzle device slide weight or ammunition choice. Each spring is made from high-strength chrome silicon a material chosen for its ability to exceed 20 000 compressions while maintaining consistent spring rate. That durability matters most on a compensated or suppressed RXM where added weight and altered gas pressure change how the slide cycles compared to a bone-stock gun. Fine-tuning the spring weight helps restore reliable function across those varying conditions. A stainless steel billet-machined non-captured guide rod ships with the kit giving the springs a solid precisely toleranced foundation to ride on during cycling. This kit is designed around the Ruger RXM specifically though it is also compatible with aftermarket copies of the pistol sharing the same architecture. Made 100 percent in the USA the kit reflects True Precision s focus on domestic manufacturing and tight quality control. For shooters running a compensated or suppressed Ruger RXM who want to eliminate malfunctions and dial in recoil feel the True Precision Recoil Spring Tuning Kit is available for sale at GrabAGun.
