Zaffiri
The Zaffiri Precision ZPS.3 G43/43X 9mm optic ready complete upper slide delivers precision engineering for shooters building or upgrading a Glock 43 or 43X. This American-made slide assembly comes fully configured with barrel, internal parts, and sights — everything you need to swap onto a compatible frame. If you're looking to improve accuracy, add an optic-ready platform, or build a custom carry or range gun, this upper gives you the quality and compatibility of a purpose-built system without the guesswork.
The slide is machined from 17-4 stainless steel in a single billet, held to tight tolerances that translate directly to more consistent performance. Black nitride finish on the threaded barrel resists corrosion and wear, and the included HD fiber sights give you a bright aiming reference right out of the box. The optic cut is engineered to accept Shield RMSc, Holosun 407K/507K, or Sig RomeoZero footprints — all three sit on the same universal mount with no rear lugs and slightly lowered front lugs, so you can swap optics without remachining. An optic cover plate is included, and mounting screws (6-32 thread) come matched to your setup; Zaffiri recommends blue Loctite to lock them in place.
Built entirely in Zaffiri's US facility, this upper is designed to fit Glock 43 and 43X frames. It's the kind of component that lets you take your carry or range gun in a direction that matches your needs — tighter tolerances, modern optic mounting, and domestic manufacturing, all without the OEM compromise.
