Zaffiri Precision Threaded Barrel for G19 Gen 3-5 | Black

The Zaffiri Precision Threaded Barrel for G19 Gen 3-5 expands a compact Glock 19-compatible build with the ability to run properly matched compensators, suppressor mounting systems, and other threaded muzzle devices. Its extended profile adds this capability while retaining the compact handling and broad component support that make the G19 platform a popular foundation for custom pistols.

Compatibility across Gen 3 through Gen 5 gives this barrel an advantage when planning a new upper or replacing components in an existing build. It can be paired with supported Glock 19-style slide assemblies from multiple generations, reducing the need to select a separate threaded barrel solely because the slide uses earlier or later locking geometry.

Zaffiri Precision machines the barrel from 416R stainless steel, then stress relieves and heat treats the material for strength and dimensional stability. The chamber, polished feed ramp, hood, and locking surfaces are precision cut to promote smooth feeding, secure engagement, and repeatable barrel positioning with compatible components.

The extended muzzle provides the necessary clearance for properly fitted 1/2 x 28 TPI accessories. A compensator can be added to support recoil-management goals, while an appropriate suppressor mounting system allows the upper to be configured for suppressed operation. When the muzzle is left bare, a correctly sized thread protector should be installed to guard the threads from impact and debris.

Black Nitride gives the barrel a durable, low-reflection surface that integrates naturally with factory-style and aftermarket slides. The dark finish produces a uniform appearance beneath a black slide while creating restrained contrast with FDE, gray, OD green, and other coated uppers. It also adds surface protection against corrosion, friction, and wear from repeated cycling.

Conventional rifling supports a broad selection of ammunition, including loads using lead, plated, and jacketed projectiles. This versatility makes the barrel suitable for practice, competition, defensive configurations, and suppressed builds without limiting ammunition selection to jacketed bullets alone.

Unlike a dedicated ported system, this non-ported barrel does not require vent openings to align with specific slide cuts. The upper can be operated with a thread protector or configured around a removable muzzle device, allowing the pistol to be adapted as performance requirements change.

The Zaffiri Precision Threaded Barrel for G19 Gen 3-5 provides a versatile foundation for a compact range pistol, compensated upper, or suppressor-compatible build. Its multi-generation fitment, Black Nitride treatment, conventional rifling, and precision-machined stainless construction allow the same barrel configuration to support a wide range of Glock 19-compatible projects.

Compatibility Note: This aftermarket barrel is designed for compatible Glock 19 Gen 3, Gen 4, and Gen 5-style pistols and components. Verify slide generation, barrel lockup, recoil-assembly clearance, muzzle-device compatibility, and bore alignment before use. Compensated or suppressed configurations may require changes to ammunition or recoil-spring weight for reliable operation. Threaded barrels and certain muzzle devices may be restricted in some jurisdictions. This product is not manufactured by, endorsed by, or affiliated with Glock.
