About
What it is, and why it matters
The Polymer80 PF940SC is Polymer80's iconic 80-percent unfinished pistol frame, designed to be home-completed into a fully functional Glock-pattern handgun (subcompact Glock 26 and 27). 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.
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.
BUILD PLATFORM: Sold by Polymer80 as an 80% frame-and-jig kit, NOT a complete serialized firearm. Builds a Glock 26/27-compatible pistol using Gen3 Glock-pattern parts. Specifications represent a typical completed build. Polymer80 discontinued all products in 2024.
