ZAFFIRI ZPS.B.43.BLK.CU.2 ZPS.B G43 UPPER 43BCPG

The ZAFFIRI ZPS.B.43.BLK.CU.2 ZPS.B G43 UPPER 43BCPG is a precision-engineered slide assembly purpose-built for the Glock 43 platform and compatible single-stack 9mm handguns. This upper receiver represents the next evolution in compact defensive and duty carry optics-ready designs, addressing the need for enhanced accuracy and modern mounting capabilities in a minimalist form factor. Law enforcement professionals and civilian carriers seeking to upgrade aging factory slides will find this Zaffiri Precision component a direct path to sub-2-inch groups at 25 yards and beyond.

Machined from hardened steel with a black melonite finish, the ZPS.B G43 upper delivers corrosion resistance and a non-reflective aesthetic suitable for tactical and concealed-carry environments. The slide geometry incorporates Zaffiri's signature aggressive rear cocking serrations—proven to function reliably in high-stress shooting and weapon transitions—while maintaining a snag-free profile ideal for appendix carry. The integrated optics-cut design accepts industry-standard micro-red dot mounts without requiring secondary adapters, enabling rapid target acquisition in low-light and dynamic scenarios. Weight-optimized at 1.09 pounds, the upper balances reciprocating mass with shooter control, reducing felt recoil and muzzle rise during rapid fire strings.

This assembly is ideal for operators and armed professionals upgrading stock Glock 43 platforms, as well as precision shooters prioritizing accuracy in a carry-class package. Installation requires basic gunsmithing knowledge or a qualified armorer; the slide mates directly to OEM or quality aftermarket Glock 43 frame/lower receivers and accepts standard G43 internals without modification. Compatibility extends to all Glock 43 trigger groups, firing pin assemblies, and recoil spring assemblies, ensuring a plug-and-play upgrade path that maintains full reliability and warranty support through Zaffiri Precision.
