Ballistic Advantage Threaded Barrel for SIG P365XL / XMacro | Copper | Non-Fluted | No LCI
The Ballistic Advantage Threaded Barrel for SIG P365XL and P365 XMacro adds 1/2×28 muzzle threads to compatible long-slide P365 configurations while retaining a smooth, non-fluted exterior. A Copper PVD finish gives the barrel a distinctive custom appearance and adds durable protection against corrosion, environmental exposure, and routine cycling wear.
This model is manufactured without a loaded chamber indicator cut. The No LCI configuration is intended for compatible SIG P365XL, P365 XMacro, and P365 XMacro TACOPS slide assemblies designed to use a non-LCI barrel.
Its 4.2-inch threaded overall length extends beyond the slide to provide clearance for compatible 9mm suppressors, compensators, and other muzzle devices. The common 1/2×28 thread pattern offers broad accessory compatibility, while the clean exterior provides a more understated alternative to Ballistic Advantage’s Spiral- and Bomber-fluted barrels.
Ballistic Advantage machines this Premium Series pistol barrel from hardened 416R stainless steel for strength, toughness, and corrosion resistance. The Copper Physical Vapor Deposition coating adds a hard, durable exterior surface while allowing the barrel to stand out through compatible slide windows and openings.
Each bore is honed, lapped, and tumbled to remove manufacturing imperfections and create a smooth internal finish. The chamber meets SAAMI specifications, and bore deviation is held to less than .0001 inch to support consistent lockup, reliable cycling, and repeatable accuracy without a manufacturer-prescribed break-in period.
