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

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

The Ballistic Advantage Threaded Barrel for SIG P365XL and P365 XMacro provides suppressor-ready functionality in a clean, non-fluted configuration. Its Black QPQ finish delivers a subdued factory-style appearance while increasing surface hardness, wear resistance, and protection against corrosion.

This model includes a loaded chamber indicator cut for compatible LCI-equipped slide assemblies. It is designed for appropriately configured SIG P365XL, P365 XMacro, and P365 XMacro TACOPS pistols and should be paired with matching loaded chamber indicator components.

The muzzle is threaded 1/2×28 for compatible 9mm suppressors, compensators, and other muzzle devices. Without exterior fluting, the barrel maintains a smooth, streamlined profile that fits builds where accessory compatibility is desired without the more aggressive appearance of a Bomber- or Spiral-fluted barrel.

Ballistic Advantage machines this Premium Series pistol barrel from hardened 416R stainless steel for strength, toughness, and long-term durability. The Black Quench Polish Quench treatment hardens the exterior surface and helps the barrel resist friction, moisture, cycling wear, and environmental exposure.

Each bore is honed, lapped, and tumbled to remove manufacturing imperfections and create a smooth internal finish. Ballistic Advantage produces the chamber to SAAMI specifications and holds bore deviation to less than .0001 inch to support consistent lockup, dependable cycling, and repeatable accuracy without a manufacturer-prescribed break-in period.
