True Precision P365XL 9mm Threaded Barrel - Titanium Nitride Finish

The True Precision P365XL 9mm threaded barrel in titanium nitride finish is a match-grade upgrade for shooters looking to tighten groups and extend the versatility of their SIG Sauer P365 XL platform. Built as a drop-in replacement, this barrel swaps directly into your XL frame and delivers the precision improvements that come from superior machining and chamber tolerances—without the guesswork of compatibility or fitting.

Machined from stainless steel and finished in titanium nitride for durability and corrosion resistance, the barrel features a 6-groove, broach-cut rifling design that handles any ammunition type you feed it, including cast-lead rounds. The 11-degree target crown and threaded muzzle (1/2-28 TPI) give you the foundation for a suppressor-ready P365 XL while maintaining the accuracy edge that comes from a fully supported, SAAMI-spec chamber. Added chamfers and radius cuts throughout the barrel reflect the attention to detail you expect from match-grade components.

If you're running your P365 XL at the range, in competition, or in the field, this True Precision barrel rewards accurate shooting and rewards your ammunition investment with tighter, more consistent groups. The titanium nitride finish stands up to regular use and cleaning, making it a practical choice for a barrel that'll see real-world handling.
