True Precision Recoil Spring Tuning Kit Sig P365XL/X Macro 3.7" 9mm Luger

The True Precision Recoil Spring Tuning Kit for the Sig P365 XL and P365 X Macro 3.7" is a complete drop-in spring system designed to let shooters dial in slide cycling for compensated or suppressed carry setups. This 9mm Luger kit gives you five progressively weighted recoil springs so you can match return force to your specific ammo and muzzle device, eliminating the slide-bite and cycling issues that often appear once a compensator or suppressor is added to a short-recoil pistol.

The kit includes five chrome silicon recoil springs - 12 LB (Red), 14 LB (Green), 16 LB (Yellow), 18 LB (Stock/Black), and 20 LB (Orange) - letting you step down from the factory 18 LB spring for lighter loads or step up to keep the slide locked when running hotter defensive ammo. A stainless steel non-captured guide rod is included for a complete, drop-in swap from the factory assembly. The chrome silicon wire used for the springs holds its rate far longer than standard spring steel under the heavy cycling demands of compensator and suppressor use, making this kit well suited for daily-carry and high-round-count shooters.

Designed and manufactured in the USA by True Precision, this tuning kit is engineered specifically for the Sig P365 XL and P365 X Macro 3.7" slide assemblies. It is intended for use with aftermarket compensators and 9mm suppressors that change the back-pressure profile of the pistol. Color-coded springs make range-time swaps quick, and the included guide rod installs without permanent modification to the firearm.
