Faxon Firearms Duty Series Barrel Features The Faxon Firearms Duty Series barrel is machined from 4150 chrome moly vanadium steel and chambered in 9mm Luger purpose built as a drop-in replacement for the Sig Sauer P365 XL. Its black nitride finish adds a protective layer against corrosion while also improving the barrel s lubricity helping keep the pistol running smoothly between cleanings. A 1:10 twist rate is matched to common 9mm bullet weights for consistent reliable accuracy. The threaded muzzle protected by an included thread protector during normal carry opens the door to mounting a suppressor when the shooter wants that added capability. As a drop-in barrel installation is straightforward for anyone comfortable performing basic maintenance on their P365 XL requiring no gunsmithing or fitting work. Faxon Firearms has built a strong reputation for precision-machined handgun and rifle barrels and the Duty Series brings that same quality to a popular compact carry pistol. Upgrading to an aftermarket threaded barrel gives P365 XL owners options for suppressor use that the factory barrel does not offer. The Faxon Firearms Duty Series barrel is available for sale at GrabAGun for P365 XL owners wanting a durable threaded barrel upgrade.
