Zaffiri Precision Upper Parts Kit 9mm Luger - Fits Glock 19 Gen 5

The Zaffiri Precision Upper Parts Kit (UPK-G19G5) is a complete set of internal slide components designed to finish out a custom Glock 19 Gen 5 slide build. Engineered specifically for the 9mm Luger Gen 5 platform, this kit provides the small parts needed inside the slide - firing pin assembly, firing pin safety, extractor, extractor depressor plunger, and the associated springs and pins - so a custom slide can be assembled to factory-spec tolerances.

Every component is manufactured in the United States by Zaffiri Precision to the original Glock specification and held to tight tolerances for reliable lockup, consistent ignition, and dependable extraction. The black finish matches factory slide internals for a clean, factory-correct look once installed.

This listing is for the parts kit only - it does not include the slide, barrel, recoil spring assembly, frame, sights, or any other component. It is intended for builders completing a custom Glock 19 Gen 5 slide and pairs naturally with a Zaffiri Precision complete upper, barrel, and optic-ready slide cover plate.
