Zaffiri Precision Threaded Barrel for P365 | Black

The Zaffiri Precision Threaded Barrel for P365 is built for shooters who want to add threaded-barrel functionality to a Sig Sauer P365-compatible pistol without stepping into a complicated custom-fit setup. Designed as a drop-in aftermarket barrel, it gives compact pistol owners a practical upgrade path for range builds, slide assembly projects, and properly configured muzzle-device setups.

Machined from 416R stainless steel at Zaffiri Precision’s facility in Largo, Florida, this barrel is made for consistent fitment with OEM and aftermarket components. The extended threaded muzzle is intended for compatible 1/2×28 TPI compensators, suppressors, and other correctly fitted accessories, while the included thread protector helps shield the muzzle threads when the pistol is being used without an installed device.

This P365-compatible barrel uses conventional rifling for broad ammunition compatibility, making it a strong option for customers shooting common lead, plated, or jacketed bullets. The polished chamber and bore support smooth operation, while the Loaded Chamber Indicator notch adds an important fitment detail for customers who need to match their barrel configuration to their pistol and applicable state requirements.

For shoppers comparing aftermarket P365 threaded barrels, this Zaffiri Precision model delivers the details that matter: U.S. manufacturing, 416R stainless steel construction, 6-groove rifling, drop-in installation, included thread protector, LCI notch, and compatibility with popular Zaffiri Precision slide families. It is positioned well for customers who want a premium barrel upgrade that adds function while keeping the P365 platform compact and familiar.

This barrel is compatible with Zaffiri Precision ZPS.2, ZPS.3, Z Series, and IBS slide models, giving builders several options for completing a custom P365 upper. Threaded pistol barrels and muzzle devices may be restricted in certain jurisdictions, so customers should confirm all local, state, and federal laws before ordering.
