Polymer80 PF9SS 80% Single-Stack Pistol Frame

The PF9SS is an 80%-style pistol frame designed for Glock 43-compatible builds, offering a compact, single-stack platform for concealed carry enthusiasts. Weighing in at just 5.5 ounces, this frame is constructed from reinforced polymer, ensuring durability while keeping the overall weight down. The PF9SS features an undercut trigger guard for improved grip and control, along with a standard Glock accessory rail for attaching lights or lasers. This frame ships with a jig and drill bits, so you’ll have everything needed to complete the machining process. Note: you’ll need to source a slide, barrel, and parts kit separately to finish your build.

The PF9SS is currently legal in most states as an unfinished receiver — verify your local + state law before purchasing. This P80-pattern frame is ideal for builders who want a lightweight, concealable option without sacrificing functionality. Whether you’re assembling your first pistol or adding to your collection, the PF9SS provides a solid foundation for a reliable carry piece. Keep it simple, keep it clean, and let the build speak for itself.
