Ballistic Advantage Standard Threaded Barrel w/ Bomber Fluting for SIG P365 | Black | LCI

Ballistic Advantage Standard Threaded Barrel w/ Bomber Fluting for SIG P365 | Black | LCI

The Ballistic Advantage Standard Threaded Barrel with Bomber Fluting for SIG P365 combines suppressor-ready 1/2×28 muzzle threads with a distinctive machined profile and durable black QPQ finish. Designed for standard-length SIG P365 and P365X configurations, this LCI barrel includes the loaded chamber indicator cut required for compatible slide assemblies.

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

Bomber fluting gives the exterior a recognizable custom profile while allowing the barrel finish to remain visible through compatible windowed slides. The black Quench Polish Quench finish increases surface hardness, wear resistance, and protection against corrosion, making it well suited to regular carry, suppressed use, and high-volume range sessions.

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

The chamber is manufactured to SAAMI specifications, and Ballistic Advantage holds bore deviation to less than .0001 inch to support consistent lockup, reliability, and accuracy. This version is specifically configured with an LCI cut and should be paired with a compatible SIG P365 or P365X slide and loaded chamber indicator assembly.
