Zaffiri Precision Side Ported Barrel for G17L Gen 3 | Black

The Zaffiri Precision Side Ported Barrel for G17L Gen 3 is a performance-focused aftermarket barrel for Glock 17L Gen 1-3-compatible long-slide pistols. Built for shooters who want recoil-management benefits without adding a threaded muzzle or external compensator, this barrel uses side porting to redirect gases laterally and help keep the pistol flatter during recoil.

The Glock 17L platform is a long-slide configuration, and that makes correct barrel fitment especially important. This Zaffiri Precision barrel is designed for Glock 17L Gen 1-3-style slides, giving builders the extended length needed for the proper long-slide setup. It should not be confused with a standard Glock 17 barrel, since the G17L uses a longer slide and requires the correct barrel format.

The side-ported layout gives this barrel a different role than a flush-and-crown or threaded option. Instead of keeping the muzzle completely plain or extending it for muzzle devices, the porting is built into the barrel itself. When paired with a compatible slide configuration, the angled porting helps redirect gas to reduce muzzle rise and felt recoil while preserving a clean, non-threaded profile.

Zaffiri Precision machines this barrel from 416R stainless steel at its facility in Largo, Florida. The barrel is built for consistent fitment and dependable operation with standard components, making it a strong choice for long-slide range pistols, custom upper assemblies, and performance-oriented G17L-compatible builds. Conventional rifling supports use with a wide range of common ammunition types, including lead, plated, and jacketed bullets.

For customers comparing aftermarket Glock 17L Gen 3 barrels, this Zaffiri Precision side-ported model is positioned for builders who want a long-slide barrel with integrated recoil-control features. It offers the correct G17L fitment, U.S. manufacturing, 416R stainless steel construction, non-threaded handling, and a purpose-built ported design for shooters who want more control from the barrel and slide combination.
