Ballistic Advantage Standard Threaded Barrel for SIG P365 | Light Gray | Non-Fluted | No LCI

Ballistic Advantage Standard Threaded Barrel for SIG P365 | Light Gray | Non-Fluted | No LCI

The Ballistic Advantage Standard Threaded Barrel for SIG P365 delivers suppressor-ready capability in a clean, non-fluted configuration. Designed for standard-length SIG P365 and P365X slides, this No LCI barrel does not include a loaded chamber indicator cut and should be used with a compatible non-LCI slide assembly.

Machined from hardened 416R stainless steel, this Premium Series barrel is built for durability, dimensional stability, and corrosion resistance. Ballistic Advantage hones, laps, and tumbles each barrel to produce a smooth, finished bore with no manufacturer-prescribed break-in period.

The non-fluted exterior maintains a streamlined profile that works well with both factory-style and custom P365 slides. A Light Gray Physical Vapor Deposition (PVD) finish adds a durable protective coating while creating a distinctive contrast against black slides, frames, and controls.

Its 3.6-inch threaded overall length extends beyond a standard P365 slide and terminates in 1/2×28 muzzle threads. This common 9mm thread pattern supports compatible suppressors, compensators, and other muzzle devices. A 1:10 right-hand twist provides dependable stabilization across commonly used 9mm projectile weights.

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 barrel is intended for compatible SIG P365 and P365X configurations that do not require an LCI cut.
