The Zaffiri Precision ZPS.2 Complete Black Slide for Glock 43 is a precision-engineered aftermarket upper assembly built for shooters who want to upgrade their compact carry gun without starting from scratch. Made from single-billet 17-4 stainless steel and finished in black, this complete slide assembly comes ready to install on your Glock 43 or 43X frame—no gunsmithing required. Zaffiri Precision manufactures these slides in-house to tight tolerances that noticeably improve accuracy and reliability compared to factory components.
This isn't just a slide. The ZPS.2 package includes a flush-and-crown barrel with black nitride finish, a full upper parts kit, and HD fiber front and rear sights out of the box. The optics cut is compatible with Shield RMSc, Holosun 407K/507K, and SIG RomeoZero red dots—all using the same footprint with no rear lugs and slightly lowered front lugs, so you can run your favorite micro red dot without compatibility headaches. An optic cover plate is included, and Zaffiri includes all necessary 6-32 mounting screws (blue Loctite recommended for proper retention).
What makes this worth the investment: American manufacturing, tight tolerances that stack up to measurably better groups, and a thoughtful design that acknowledges the reality of modern carry optics. Whether you're running your Glock 43 for concealed carry, duty, or the range, the ZPS.2 gives you a professional-grade upper that feels and shoots noticeably tighter than stock.

Yes. The ZPS.2 is designed to fit Glock 43 and 43X frames. The complete upper assembly installs on your existing frame—you're not building from a serialized lower.
The slide features a unified optics cut compatible with Shield RMSc, Holosun 407K/507K, and SIG RomeoZero red dots. All three share the same footprint on this slide (no rear lugs, slightly lowered front lugs), so you can run whichever micro red dot you prefer. The optic mount sits forward of the factory rear iron sight location.
The ZPS.2 comes complete with the barrel, upper parts kit, sights, optic cover plate, and mounting screws. You'll install it on your existing Glock 43 or 43X frame. Blue Loctite is recommended for optic screw retention but is not included.
