True Precision Sig P365 9mm Luger 3.10" Black Nitride Stainless Steel Drop-In Barrel

The True Precision TPP365BXBL is a drop-in replacement barrel for the Sig Sauer P365 platform, machined from 416R stainless steel and finished in a durable, low-friction Black Nitride coating. Designed as a direct swap for the factory barrel, it installs without gunsmithing or permanent modifications to the slide.

Chambered in 9mm Luger, this barrel measures 3.10" overall and features a 1:10" right-hand twist with a broach-cut 6-groove rifling pattern for consistent accuracy across a wide range of 9mm bullet weights. The non-threaded profile is purpose-built for the compact Sig P365, P365 SAS, and P365-AXG Legion pistols, making it a clean, no-gunsmithing upgrade.

Offered with no sights for shooters who rely on factory slide-installed sights or co-witnessed optics, this True Precision barrel is a straightforward upgrade for everyday carry, range work, and competition use.
