Product Description The True Precision Recoil Spring Tuning Kit is a premium upgrade engineered specifically for the Ruger RXM pistol and its aftermarket copies, with extended compatibility for Glock Gen 1-3 and Gen 6 pistols as well. Ideal for shooters running a compensator or suppressor, this kit enables precise tuning of your recoil system for reliable cycling and noticeably reduced felt recoil across a wide range of configurations. Every spring in the kit is manufactured from high-strength chrome-silicon, delivering consistent, long-lasting performance rated at over 20,000 compressions per spring. The included stainless steel billet-machined non-captured guide rod allows for fast, tool-free spring changes while eliminating a common point of failure found in standard captured guide rod designs. With six distinct spring weight options, you can dial in your pistol for virtually any combination of slide weight, ammunition type, and muzzle device. Proudly 100% Made in the USA.
