ZAFFIRI ZPS.2.19.BLK.CU ZPS.2 G19 G3 UPPER 19BBN

The Zaffiri Precision ZPS.2 G19 G3 Upper (Model ZPS.2.19.BLK.CU) is a complete drop-in upper assembly engineered for Glock 19 Generation 3 platforms. This single-piece billet 17-4 stainless steel slide delivers the tight tolerances and precision machining that distinguish premium aftermarket uppers from standard factory components. Manufactured in-house at Zaffiri Precision's U.S. facility, the ZPS.2 assembly combines a match-grade barrel, precision-fitted internals, and integrated sighting provisions designed for shooters prioritizing accuracy and reliability over extended duty cycles.

The ZPS.2 features a flush-crown barrel design that minimizes external snag hazards during holster transitions and equipment handling—a practical consideration for both tactical operators and concealed-carry users. The upper is pre-configured with mounting provisions compatible with popular pistol-mounted optics, including Trijicon RMR and SRO systems, as well as Holosun 407C, 507C, and 508T red-dot sights. The billet construction and American manufacturing process ensure consistent dimensions across production units, reducing the fit and function variables that can compromise reliability in critical situations. Weighing 1.19 pounds, the assembly maintains balance within the Glock 19's ergonomic envelope.

This upper suits law enforcement trainers, competitive shooters, and experienced handgun users who demand precision-grade components for accuracy-focused builds. The modular design allows integration with existing Glock 19 Gen 3 lower receivers, making it accessible to those upgrading slide assemblies without committing to a complete firearm replacement. For users operating optic-ready platforms or seeking performance gains through tight-tolerance engineering, the ZPS.2 represents a significant step above factory specifications. Serious shooters evaluating Glock 19 Gen 3 upper options should compare the ZPS.2's billet-steel construction and American manufacturing pedigree against competing options to understand the precision trade-offs available in the aftermarket segment.
