Ballistic Advantage Standard Threaded Barrel for SIG P365 | Copper | Non-Fluted | LCI

The Ballistic Advantage Standard Threaded Barrel for SIG P365 delivers suppressor-ready capability in a clean, non-fluted configuration with a distinctive Copper PVD finish. Designed for standard-length SIG P365 and P365X pistols, this LCI barrel includes the loaded chamber indicator cut required for compatible factory and aftermarket slide assemblies.

Ballistic Advantage machines this Premium Series barrel from hardened 416R stainless steel for strength, toughness, and resistance to corrosion. Each bore is honed, lapped, and tumbled to remove manufacturing imperfections and create a smooth internal surface that requires no manufacturer-prescribed break-in period.

The smooth exterior maintains a streamlined, factory-inspired profile without decorative fluting. A Copper Physical Vapor Deposition coating gives the barrel a durable protective surface and a high-contrast appearance that pairs especially well with black, gray, FDE, or windowed slides.

The muzzle is threaded 1/2×28 for compatible 9mm suppressors, compensators, and other muzzle devices. Its 1:10 right-hand twist supports commonly used 9mm projectile weights for defensive ammunition, training loads, competition use, and suppressed shooting.

Ballistic Advantage chambers the barrel to SAAMI specifications and holds bore deviation to less than .0001 inch to support consistent lockup, reliability, and accuracy. This model is specifically configured with an LCI cut and should be installed in a compatible SIG P365 or P365X slide designed to use a loaded chamber indicator barrel.
