Ballistic Advantage Standard Threaded Barrel w/ Bomber Fluting for SIG P365 | Black | No LCI

Ballistic Advantage Standard Threaded Barrel w/ Bomber Fluting for SIG P365 | Black | No LCI

Upgrade a SIG Sauer P365 or P365X with a premium threaded barrel engineered for accuracy, durability, and distinctive styling. This Ballistic Advantage Premium Series barrel combines hardened 416R stainless steel construction with Bomber fluting, a corrosion-resistant black QPQ finish, and a suppressor-ready 1/2×28 threaded muzzle.

The 3.6-inch threaded configuration extends beyond the slide to accommodate compatible suppressors, compensators, and other 9mm muzzle devices. A 1:10 right-hand twist provides dependable stabilization across commonly used 9mm bullet weights, making the barrel well suited to defensive ammunition, range loads, and suppressed shooting configurations.

Ballistic Advantage hones, laps, and tumbles each barrel to produce a smooth, consistent bore with no manufacturer-prescribed break-in period. Bore deviation is held to less than .0001 inch, supporting consistent projectile travel and accuracy while maintaining the dimensional tolerances required for reliable operation in compatible factory pistols.

Bomber fluting gives the exterior a distinctive machined profile while setting the barrel apart from conventional non-fluted replacements. The black QPQ treatment increases surface hardness, wear resistance, and corrosion protection while providing a low-maintenance finish suited to regular carry and high-volume range use.

This version is manufactured without a loaded chamber indicator cut. It is designed for compatible standard-length SIG Sauer P365 and P365X configurations and should be used with slides that do not require an LCI barrel. As with any precision-fit pistol component, installation and function should be verified before live fire.
