KCI USA Lower Parts Kit – Fits Glock 43

This KCI USA lower parts kit provides all the essential small components needed to complete or repair a Glock 43 frame. Designed for builders working with aftermarket frames or shooters replacing worn or damaged factory parts, this kit includes trigger housing components, pins, springs, and other critical lower receiver hardware. It's a practical solution for home builders or armorers maintaining multiple firearms.

Manufactured to meet OEM specifications, these parts are precision-machined for proper fit and function in Glock 43 frames. Installation requires basic gunsmithing knowledge and appropriate punch tools. While many components are straightforward drop-ins, familiarity with Glock disassembly and reassembly procedures is essential.
