Faxon Firearms Match Series 9mm Luger 3.7" Fluted Threaded Barrel - Black Nitride - Sig P365 XL

The Faxon Firearms Match Series drop-in pistol barrel is a match-grade replacement for the Sig Sauer P365 XL chambered in 9mm Luger. Machined in-house from stress-relieved 416-R stainless steel and finished in Black Nitride, this 3.7" barrel is engineered to deliver top-tier accuracy, durability, and corrosion resistance in a compact slide profile.

The straight-fluted profile sheds weight and adds distinctive styling along with extra surface area for cooling. A precision target crown protects the muzzle and promotes consistent bullet release, while the 1/2x28 threaded muzzle accepts common 9mm compensators, suppressors, and thread adapters for suppressor-ready or compensated builds.

Featuring a 1:10 twist and a true drop-in fit, this barrel installs directly into the P365 XL slide with no fitting or modification required, giving shooters an immediate upgrade in accuracy and the versatility of a threaded muzzle. Like every Faxon barrel, it is manufactured in the USA under strict quality standards.
