Building a custom Gen 5 Glock slide becomes straightforward when you have all the right components in one kit. The Zaffiri Precision ZAF Upper Parts Kit is engineered to the tightest tolerances and original factory specifications, ensuring your slide assembly functions reliably from the first round.
This kit includes thirteen individual components working together as a complete system. The firing pin assembly comes with a spring, spacer sleeve, and channel liner. You'll also find two spring cups, the nitride-treated firing pin safety and its spring, plus the extractor depressor plunger with its spring and bearing. The slide cover plate provides a finished look while the upgraded stainless steel recoil spring assembly handles the mechanical demands of every shot. Several components receive nitride treatment for enhanced corrosion resistance and durability.
Zaffiri manufactures all parts domestically to the highest tolerances. This kit is engineered specifically for Gen 5 models and will not fit earlier Glock generations, so double-check your slide generation before ordering. The attention to detail ensures consistent fit and function across the wide variety of aftermarket and custom slides available today. Each part is made to support reliable ignition, positive extractor engagement, and durable slide operation even under high round-count use.
Many upper parts kits skimp on the recoil spring assembly, forcing you to source it separately. This kit includes an upgraded ZP stainless steel guide rod with OEM spring weight, saving you both money and the guesswork of matching components. The recoil assembly represents a significant portion of kit cost on its own, making this all-in-one approach a practical choice for builders who want quality components they can trust.
No. This kit is engineered specifically for Gen 5 models and will not fit Gen 1, 2, 3, or 4 slides. Zaffiri offers separate kits for earlier generations. Double-check your slide generation before ordering to ensure proper fit.
Installation requires familiarity with Glock slide assembly and proper tools. We recommend having a qualified gunsmith handle the work unless you have experience building slides. The components are precision-fit and improper installation could result in malfunctions.
The upgraded ZP stainless steel guide rod offers superior corrosion resistance compared to standard polymer versions, while maintaining OEM spring weight for reliable cycling. Many aftermarket kits skip this component, making it a significant value-add in this complete package.
Nitride coating enhances durability and corrosion resistance on high-wear components like the firing pin safety and extractor depressor plunger. This treatment reduces friction and improves the longevity of parts that experience repeated cycling.
