Zaffiri Precision P365XL Threaded Barrel 9mm 3.75" 1/2x28 Black Nitride

The Zaffiri Precision P365XL Threaded Barrel is a drop-in aftermarket barrel purpose-built for the SIG Sauer P365XL micro-compact pistol. Machined from 416R stainless steel and finished in a low-friction Black Nitride coating, this 9mm Luger barrel is engineered for shooters who want improved accuracy and the ability to mount muzzle accessories on their factory P365XL slide.

The 3.75" barrel features broach-cut, 6-groove rifling, a SAAMI-spec chamber, a target crown, and an oversized lock-up for tight slide fit and consistent shot-to-shot performance. Each barrel is stress relieved and heat treated to RC 40-42 for long service life under heavy use, and a 1/2x28 threaded muzzle accepts compensators, suppressors, or other 9mm muzzle devices, with a thread protector included.

Designed as a direct drop-in replacement for the factory P365XL barrel, this threaded barrel installs without permanent modification and is a popular upgrade path for EDC carriers and competitive shooters looking to expand the capability of their P365XL. Backed by Zaffiri Precision's reputation for tight-tolerance aftermarket pistol components, the BA-P365XL-TH-BN delivers match-grade performance in a package that bolts right into your existing slide.
