KCI USA Lower Parts Kit, Glock 43

The KCI USA Lower Parts Kit, Glock 43 (brand part no. CDIP-003943) supplies the internal lower-frame components needed to complete a Glock 43 build. KCI USA builds this kit specifically to Glock 43 specifications, giving a builder or armorer the frame-side parts needed to finish out a stripped Glock 43 frame without sourcing individual components separately. The Glock 43 is a single-stack subcompact, and its internal geometry differs from larger double-stack Glock models, so a model-specific kit matters for correct fitment. For anyone building a Glock 43 from a stripped frame or working through a repair, a matched kit saves time compared to piecing parts together from multiple sources.
