The True Precision P365XL 9mm stainless steel threaded barrel is a match-grade upgrade built for shooters who want tighter groups and smoother function from their SIG Sauer P365 XL. If you're running a compact 9mm that's already proven itself as a reliable carry gun, stepping up to a precision barrel is one of the smartest moves you can make—it's a drop-in replacement that transforms accuracy without requiring a trip to the gunsmith.

This barrel starts with stainless steel and adds match-grade machining throughout. The 6-groove, broach-cut rifling design is versatile enough to handle any 9mm ammunition you feed it, whether that's factory rounds or cast-lead handloads. The 11-degree target crown is cut to exacting standards, and the chamber is fully supported and held to SAAMI specification. Details like precision chamfers and radius cuts show up throughout—small touches that compound into meaningful performance gains downrange.

The threaded design (1/2-28 TPI) opens the door to sound suppressors if that's part of your long-term plan. Whether you're setting up a dedicated match gun, improving your carry platform's accuracy, or simply want to squeeze every bit of precision out of your P365 XL, this barrel delivers the kind of engineering and attention to detail that separates quality aftermarket parts from the rest of the pack.
