The Zaffiri Precision Bbl P320c Ported Gold Barrel is a match-grade replacement barrel engineered for shooters serious about accuracy and reliability. Built in the USA from 416R stainless steel, this drop-in upgrade transforms your Sig Sauer P320c into a tighter, more precise platform without gunsmithing. The ported design helps manage recoil and muzzle rise, making it an excellent choice for competitive shooters, frequent range users, and anyone looking to squeeze better performance from their compact 9mm.

This barrel arrives ready to run. The polished chamber and bore are manufactured to exacting tolerances and will cycle lead, plated, and jacketed ammunition reliably. Broach-cut rifling with a 1-in-10 twist stabilizes 9mm projectiles consistently, and stress relief and heat treatment to RC 40-42 hardness ensure durability across thousands of rounds. Whether you're dialing in for competition, practicing defensive drills, or refining your carry gun's accuracy, this is the kind of purpose-built upgrade that pays dividends downrange.

Important: This ported barrel is engineered specifically for Zaffiri Precision ZPS.4, ZPS.5, and ZPS.P slides. It will drop into a standard P320c frame, but compatibility with aftermarket slides requires verification. If you're running a factory Sig slide or third-party P320c platform, confirm fit before ordering.

Frequently Asked Questions

Will this ported P320c barrel fit my compact Sig Sauer P320?

This barrel is engineered as a drop-in fit for the Sig Sauer P320c frame. However, it is optimized for Zaffiri Precision ZPS.4, ZPS.5, and ZPS.P slides. If you're using a factory Sig slide or other third-party aftermarket slide, verify compatibility before purchase to ensure proper function.

What ammunition does this barrel shoot reliably?

The polished chamber and bore are designed to cycle lead, plated, and jacketed 9mm ammunition reliably. It chambers to 9mm SAAMI specification.

How does the ported design affect the barrel?

The porting vents gas upward from the barrel, which helps reduce muzzle rise and manage felt recoil — useful for competitive shooting, rapid follow-up shots, and overall control. The tradeoff is increased blast and flash, particularly with reduced loads.

Is this barrel manufactured in the USA?

Yes, this Zaffiri Precision barrel is precision manufactured in the USA to match-grade standards.
