As a leading choice for DIY builders, the Polymer80 PF9SS 80% pistol frame only offers a reliable platform compatible with popular slide and barrel components.

Overview

The Polymer80 PF9SS 80% pistol frame only is an unfinished, un-serialized frame designed for the single-stack 9mm platform. It arrives as a raw polymer casting requiring final milling and drilling to accept all internal components. This frame is the direct successor to the PF9 platform, refined for improved ergonomics and compatibility. Whether you are a first-time builder or an experienced gunsmith, this component delivers the flexibility to assemble a fully functional pistol without the transfer paperwork associated with a completed firearm. The frame includes all necessary jigs and instructions to guide you through the completion process.
