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

The Ballistic Advantage Standard Threaded Barrel for SIG P365 adds suppressor-ready capability while retaining a clean, non-fluted exterior. 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.

Machined from hardened 416R stainless steel, this Premium Series barrel is engineered for durability, corrosion resistance, and consistent dimensional stability. Ballistic Advantage hones, laps, and tumbles each bore to remove manufacturing imperfections and create a smooth internal finish with no manufacturer-prescribed break-in period.

The non-fluted profile maintains a streamlined, factory-inspired appearance that works well with both solid and windowed slides. A black Quench Polish Quench finish increases surface hardness and resistance to wear and corrosion while providing a low-maintenance exterior suited to everyday carry and frequent range use.

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 reliable stabilization across commonly used 9mm projectile weights.

Ballistic Advantage manufactures the chamber to SAAMI specifications and holds bore deviation to less than .0001 inch to support consistent lockup, reliability, and accuracy. This model is specifically configured for compatible P365 and P365X slides designed to use a barrel with a loaded chamber indicator cut.
