Ballistic Advantage Threaded Barrel for SIG P365XL / XMacro | Light Gray | Non-Fluted | LCI

Ballistic Advantage Threaded Barrel for SIG P365XL / XMacro | Light Gray | Non-Fluted | LCI

The Ballistic Advantage Threaded Barrel for SIG P365XL and P365 XMacro provides suppressor-ready versatility in a clean, non-fluted configuration. Finished in Light Gray PVD, it adds a refined contrast to compatible slides while retaining a streamlined exterior without decorative machining.

This version includes a loaded chamber indicator cut and is intended for compatible P365XL, P365 XMacro, and P365 XMacro TACOPS slide assemblies configured to use an LCI barrel. The extended muzzle is threaded 1/2×28 for compatible 9mm suppressors, compensators, and other muzzle devices.

Ballistic Advantage manufactures this Premium Series pistol barrel from hardened 416R stainless steel. The material combines strength, toughness, and corrosion resistance for defensive carry, regular training, and suppressed use. Its Light Gray Physical Vapor Deposition coating adds a durable protective surface that resists routine wear and environmental exposure.

The smooth, non-fluted profile offers a more understated appearance than Ballistic Advantage’s Spiral- and Bomber-fluted options. It is a strong fit for P365XL and XMacro builds where muzzle-device compatibility and a distinctive barrel finish are desired without an aggressive exterior pattern.

Each barrel is honed, lapped, and tumbled to remove manufacturing imperfections and create a smooth finished bore. The chamber is produced to SAAMI specifications, while bore deviation is held to less than .0001 inch to support reliable lockup, consistent cycling, and repeatable accuracy without a manufacturer-prescribed break-in period.
