Why Upgrade to a True Precision P365XL Barrel

• 416R Stainless for Accuracy: Barrel-grade stainless delivers uniformity and heat stability for tight, repeatable groups over high round counts.

• Gold, Carry-Ready Finish: The tough gold PVD/TiN-style coating helps fight holster wear, sweat, and humidity while keeping glare low and style high.

• True Drop-In Fit: Dimensioned specifically for the Sig Sauer P365XL slide; most pistols require no gunsmithing.*

• Enhanced Lockup Geometry: Precisely cut hood/lug surfaces support consistent lockup and a more stable point of impact.

• Optimized Chamber & Ramp: Designed for smooth cycling with SAAMI-spec 9mm ammunition (FMJ and many JHP profiles).**

• Precision Target Crown: Safeguards the muzzle and supports long-term accuracy.

*Manufacturing tolerances vary. Always perform thorough safety and function checks after installation.
**Always validate 100% reliability with your chosen carry ammo before EDC.
