Polymer80 PF9SS 80% Single-Stack Frame and Jig Kit (Glock 43 Compatible)

Overview

The Polymer80 PF9SS 80% Single-Stack Frame and Jig Kit is a precision-engineered platform designed for builders seeking a compact, single-stack 9mm pistol compatible with Glock 43 components. This kit includes the unfinished 80% frame and the necessary jig to complete the frame at home. As a true 80% lower, it requires machining of the fire control pocket, trigger pin holes, and rail system. The kit is manufactured to tight tolerances, ensuring proper fitment with OEM and aftermarket Glock 43 slides, barrels, and lower parts kits. Whether you are building a dedicated concealed carry piece or a spare frame, this kit delivers a reliable foundation without the need for serialization when kept as a personal build.
