Zaffiri Precision P365XL Threaded Barrel | Spectrum

The Zaffiri Precision Threaded Barrel for P365XL in Spectrum is a premium aftermarket barrel upgrade designed for builders who want improved performance, clean fitment, and a standout finish for their Sig Sauer P365XL-compatible pistol. Precision manufactured in the USA, this 9mm threaded barrel is built as a drop-in replacement for the P365XL platform, giving shooters a high-quality upgrade without requiring a complicated fitting process.

Machined from 416R stainless steel, this Zaffiri Precision P365XL threaded barrel is engineered for strength, consistency, and long-term durability. The barrel features a SAAMI-spec chamber, polished chamber and bore, and conventional broach-cut 6-groove rifling. That conventional rifling design helps support reliable performance with lead, plated, and jacketed bullets, making it a practical choice for a wide range of common 9mm ammunition types.

The 1/2×28 threaded muzzle gives this barrel added versatility for compatible muzzle devices, compensators, and other properly fitted threaded accessories. A thread protector is included, helping protect the muzzle threads when an accessory is not installed. The oversized lock-up area, target crown, fully supported chamber, and improved feed ramp design all contribute to the barrel’s performance-focused construction.

The Spectrum PVD finish gives this P365XL-compatible barrel its distinctive multi-tone appearance while also adding a durable, corrosion-resistant surface treatment. For builders looking to move beyond a plain stainless or black barrel, the Spectrum finish delivers a custom look that pairs well with aftermarket slides, upgraded controls, and other personalized P365XL components.

This Zaffiri Precision barrel is an excellent option for anyone upgrading a Sig Sauer P365XL-compatible build with a match-grade threaded barrel that balances performance, appearance, and straightforward installation. Whether you are replacing a factory barrel, completing a custom slide assembly, or adding threaded capability to your compact 9mm platform, this barrel provides the fit, finish, and manufacturing quality Zaffiri Precision is known for.
