Also known as: PF9SS

Overview

The Polymer80 PF9SS is Polymer80's iconic 80-percent unfinished pistol frame, designed to be home-completed into a fully functional Glock-pattern handgun (single-stack subcompact Glock 43). Sold as a frame-and-jig kit rather than a complete firearm, it is built from glass-reinforced nylon polymer and is compatible with Gen3 Glock fire-control and slide components. The frame features Polymer80's hallmark ergonomics: an aggressive grip texture, redesigned grip angle, double-undercut trigger guard, extended beavertail and a thumb ledge. Once finished with the included jig and bits, the builder installs a compatible slide assembly to produce a complete pistol. The specifications listed reflect a representative completed build on this platform.

Background

Polymer80 was founded in 2013 in Dayton, Nevada by Loran Kelley Jr. and David Borges, rising to prominence as the dominant maker of 80-percent unfinished pistol frames that let hobbyists legally build their own Glock-pattern handguns at home. The company became a flashpoint in the 'ghost gun' debate; following years of regulatory and legal pressure under ATF Final Rule 2021R-05F, Polymer80 ceased operations in 2024.
