Zaffiri Precision Threaded Barrel for SIG P365 3.75" – Black Nitride Finish

This Zaffiri Precision threaded barrel replaces the factory barrel in your SIG P365, enabling the use of suppressors or muzzle devices while maintaining reliable cycling and accuracy. The 3.75-inch length matches the P365XL slide profile, and the 1/2x28 thread pitch is standard for 9mm accessories. Black nitride finish provides corrosion resistance and reduces friction for consistent function.

Drop-in installation requires no gunsmithing—simply field strip your P365XL as normal and swap barrels. Machined from 416R stainless steel with match-grade tolerances. Thread protector included. Verify your P365 model and slide length before ordering; this barrel is designed for the XL slide configuration, not the standard 3.1-inch P365.
