Polymer80 PF940SC 80% Subcompact Pistol Frame Kit

The PF940SC is an 80%-style subcompact pistol frame designed for Glock 26 Gen 3 builds. This P80-pattern frame ships as an unfinished receiver with a pre-machined jig and drill bits — you’ll need to source a slide, barrel, and LPK separately. Weighing 5.6 oz in reinforced polymer, it’s built for concealed carry with a streamlined trigger guard and improved undercut for a tighter grip. The front rail accepts standard Glock-style slide components.

Right out of the box, the PF940SC has aggressive texturing where it counts and a flared magwell for faster reloads. The frame’s geometry mirrors factory Glock ergonomics but leaves room for customization — stipple it, undercut it further, or leave it raw. The included jig is pre-marked for easy drilling, and the polymer material takes standard gunsmithing tools without cracking. Currently legal in most states as an unfinished receiver — verify your local + state law.

This isn’t a parts kit or a complete gun. It’s a project for builders who care about fitment. The PF940SC works with OEM Glock 26 slides or aftermarket options, but double-check your slide’s compatibility with Gen 3 specs. No serialization, no FFL needed unless your state requires it post-build.
