Zaffiri Precision Stainless Steel Guide Rod for Glock^® G17 / G34 Gen 4

The Zaffiri Precision Stainless Steel Guide Rod for Glock^® G17 / G34 Gen 4 is a performance-driven upgrade designed to improve stability, reduce recoil, and offer long-term durability for Gen 4 models. Built to fit both Glock® 17 and Glock® 34 Gen 4 pistols, this guide rod replaces the standard polymer assembly with a precision-machined stainless steel component that delivers enhanced cycling and a more solid shooting experience.

This drop-in replacement is machined from high-grade stainless steel, giving it a noticeable increase in mass compared to factory units. That added weight helps reduce muzzle flip and recoil impulse, providing quicker target reacquisition for follow-up shots. Whether you’re running high round counts during training or optimizing for competition use, the stainless steel design maintains consistent performance and resists deformation over time.

Engineered for exact Gen 4 compatibility, this guide rod offers a direct fit for Glock^® 17 and Glock® 34 models without modification. It retains OEM spring dimensions and function while increasing overall system durability. The smooth stainless finish not only adds a sleek appearance but also resists fouling, corrosion, and wear from extended use.

Installation is simple for experienced Glock^® owners, but professional gunsmithing is always recommended to ensure proper fitment and safe function. The added rigidity of the Zaffiri Precision design also improves slide tracking and eliminates flex that may be present in plastic OEM components. Shooters looking for a mechanical edge, whether in speed or repeatability, will immediately appreciate the difference this guide rod offers.

Please note: this guide rod is only compatible with Glock® 17 and Glock® 34 Gen 4 models and is not intended for use with Gen 3 or Gen 5 pistols. It is not compatible with other Glock® platforms or variants.
