Zaffiri Precision UPK-G4348 Upper Slide Parts Kit - Fits Glock 43/43X/48

The Zaffiri Precision UPK-G4348 is a complete upper slide parts kit designed to fit Glock 43, 43X, and 48 pistols. This aftermarket kit supplies every small internal slide component needed to finish out a custom slide build or to service worn factory internals, packaged in one convenient set.

The UPK-G4348 includes the firing pin and spring, spring cups, and the safety plunger and spring - the critical hardware that sits in the top of the slide and interfaces with the firing pin channel and breech face. Every part is made in the USA to Zaffiri Precision's tight tolerances for a precise, drop-in fit on the slim-frame 9mm Luger Glock 43, 43X, and 48 platforms.

Designed for slide builders and gunsmiths completing a custom Glock 43-series or Glock 48 slide, the UPK-G4348 is an ideal complement to Zaffiri Precision complete upper slides or any compatible aftermarket slide for the standard G43 / G43X / G48 configuration.
