Zaffiri Precision Threaded Barrel for G34 Gen 3 | Stainless

The Zaffiri Precision Threaded Barrel for G34 Gen 3 is a premium aftermarket barrel for Glock 34 Gen 3 and Gen 4-compatible pistols. Designed around the longer Glock 34 slide profile, this barrel adds muzzle-device capability to a full-size platform commonly used for range pistols, competition-style builds, and custom slide assemblies where extended sight radius, balance, and configuration flexibility all matter.

Correct G34 fitment is the foundation of this upgrade. The Glock 34 uses a longer barrel and slide format than a standard Glock 17, so this Zaffiri Precision barrel is built for Glock 34 Gen 3 and Gen 4-style slides rather than standard Glock 17 slides. That gives the pistol the proper extended barrel profile while maintaining drop-in installation with compatible components.

The extended threaded muzzle supports properly matched compensators, suppressors, and other compatible muzzle devices. This configuration gives the Glock 34 platform more tuning potential than a flush-and-crown barrel, while still preserving the full-size handling characteristics that make the G34 popular for precision-oriented range use and competition-style builds.

Zaffiri Precision machines this barrel from 416R stainless steel at its facility in Largo, Florida. Conventional rifling supports a wide range of common ammunition types, including lead, plated, and jacketed bullets. The barrel is designed for dependable operation with standard components, making it a practical upgrade for properly configured Glock 34 Gen 3 and Gen 4 pistols.

This Zaffiri Precision threaded barrel is also compatible with Zaffiri Precision ZPS.2, ZPS.3, Z Series, and IBS slide models. It is best suited for Glock 34-compatible builds that need U.S.-made construction, precision-machined fitment, conventional rifling, and threaded muzzle capability in one long-slide barrel.
