True Precision Inc P365 X-Fluted Match Grade Barrel - Gold Titanium Nitride for Sig P365

The True Precision P365 X-Fluted Match Grade Barrel for Sig P365 is a precision-built drop-in replacement designed to tighten groups and improve reliability in one of the most popular compact carry guns on the market. Built from US-sourced 416R match-grade stainless steel and manufactured to strict tolerances, this barrel uses True Precision's proprietary broach-cut rifling process to deliver the accuracy potential your P365 is capable of. Whether you're running it as an EDC upgrade, a range gun, or a competition platform, this barrel holds up to the kind of scrutiny competitive shooters and serious defensive shooters apply to their gear.

The gold titanium nitride finish isn't just for looks—it's a durable, low-friction coating that resists corrosion and wear. The fluted profile reduces weight without sacrificing rigidity, and the polished feed ramp ensures smooth, reliable feeding across a wide range of ammunition. Heat-treated to Spec 42–44 Rc hardness, the barrel is built to last through thousands of rounds and maintain its accuracy.

True Precision sets itself apart by going beyond standard tolerances and finishing. The competition-style crown on this non-threaded barrel promotes equal gas dispersion for improved shot-to-shot consistency. Combined with the 1/10 twist rate optimized for the P365 platform and a SAAMI-spec chamber, this is a serious upgrade for shooters who want their compact carry gun to perform like a precision instrument.

What's the difference between this and a factory P365 barrel?
