Ballistic Advantage Standard Threaded Barrel w/ Spiral Fluting for SIG P365 | Copper | LCI

Ballistic Advantage Standard Threaded Barrel w/ Spiral Fluting for SIG P365 | Copper | LCI

The Ballistic Advantage Standard Threaded Barrel with Spiral Fluting for SIG P365 combines suppressor-ready capability with a distinctive Copper PVD finish and loaded chamber indicator compatibility. Designed for standard-length SIG P365 and P365X configurations, 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 long-term corrosion resistance. Each bore is honed, lapped, and tumbled to remove machining imperfections and create a smooth internal surface that requires no manufacturer-prescribed break-in period.

Spiral fluting gives the exterior a flowing machined profile that remains visible through compatible slide windows and relief cuts. The Copper Physical Vapor Deposition coating adds a durable protective surface while creating a high-contrast appearance against black, gray, FDE, or stainless slide finishes.

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

Ballistic Advantage manufactures the chamber to SAAMI specifications and holds bore deviation to less than .0001 inch to support consistent lockup, accuracy, and dependable operation. This version is specifically intended for compatible SIG P365 and P365X slides configured to use an LCI barrel.
