True Precision Barrel P365xl 9mm Copper Threaded Barrel

The True Precision Barrel P365xl 9mm Copper Threaded Barrel is a direct replacement barrel designed for the SIG Sauer P365 XL platform. This threaded barrel accommodates suppressor use and extends the accessory ecosystem for shooters seeking modularity and sound mitigation in 9mm configurations.

The threaded design allows installation of standard 9mm suppressors or muzzle devices, while maintaining the precision tolerances required for reliable function and accuracy. Copper plating on the threads provides corrosion resistance and facilitates easier removal after extended suppressed fire, a practical consideration for shooters who regularly shoot suppressed. The barrel dimensions and geometry are engineered to function within the P365 XL slide and frame specifications, ensuring proper cycling and slide lock after the final round.

This barrel serves shooters who prioritize noise reduction at the range or in low-light tactical applications, as well as competitive shooters exploring suppressed division events. Replacement barrels are favored by firearms owners who want to add threading capability to an existing P365 XL without purchasing an entirely new pistol, or who wish to maintain a non-threaded barrel for everyday carry while keeping a suppressor-ready option. Installation typically requires basic firearms maintenance knowledge and standard tools.

The SIG Sauer P365 XL platform remains one of the most popular compact 9mm carry pistols, and aftermarket barrel options expand its utility across multiple shooting disciplines. Threaded barrels in this segment represent a growing category for shooters integrating suppressors into their duty and sport load-outs.
