Building a custom Glock slide? The Zaffiri Precision Upper Parts Kit (UPK) for Glock 17/34/17L Gen 1–3 gives you a complete set of factory-specification components to finish your build the right way. Whether you're assembling a competition pistol, a carry gun, or a range workhorse, this kit includes every internal part you need to get your upper working reliably—and everything is manufactured in the USA to tight tolerances that match original Glock specs.
Zaffiri Precision has built a reputation among serious shooters for precision machining and uncompromising quality. This UPK takes the guesswork out of sourcing individual parts; you get a matched set engineered to work together, which means fewer compatibility headaches and faster assembly. The kit is designed for the Glock 17, long-slide G17L, and G34—across generations 1 through 3—so whether you're upgrading a classic or modernizing an older frame, you have the right parts on hand.
One important note: this is a kit for competent gunsmiths or experienced builders. Installation requires the knowledge and tools to disassemble and reassemble a Glock upper receiver. If you're new to building, consider having a qualified gunsmith handle the work. And remember—this is an aftermarket product not manufactured or endorsed by Glock; make sure it suits your needs before ordering.
