Polymer80 PF9SS 80% Single-Stack Frame and Jig Kit (Glock 43 Compatible)

Overview

The Polymer80 PF9SS 80% Single-Stack Frame and Jig Kit is a precision-engineered platform for building a compact, single-stack pistol compatible with Glock 43 components. Designed for hobbyists and builders who demand control over their firearm’s ergonomics and trigger feel, this kit includes the unfinished frame and the necessary jig system to complete the build at home. The polymer80 pf9ss 80% single-stack frame and jig kit (glock 43 compatible) requires no serial number and is not a firearm under federal regulations until machining is complete. It delivers a factory-like fit with standard Glock 43 parts, allowing you to assemble a reliable, custom-carry pistol from the ground up.

Features & Specs

Manufactured by Polymer80, this frame kit is built from high-strength, impact-resistant polymer with a reinforced rail system. The jig includes hardened steel drill bushings and alignment blocks to ensure accurate hole placement for the trigger mechanism and locking block. The PF9SS frame is designed to accept all factory Glock 43 internal components, slide assemblies, and magazines without modification. Key specifications include a single-stack magazine well, a standard 1913 Picatinny rail section on the dust cover, and an ergonomic grip angle that mirrors the OEM Glock 43 profile.

Who It’s For

This kit is intended for experienced firearm builders, DIY enthusiasts, and individuals who prefer a custom-fit concealed carry platform. If you already own or plan to acquire a Glock 43 slide assembly, barrel, and lower parts kit, the polymer80 pf9ss 80% single-stack frame and jig kit (glock 43 compatible) provides the foundation for a lightweight, single-stack pistol tailored to your hand. It is ideal for those who want to avoid the cost of a complete factory firearm while gaining hands-on knowledge of the trigger group and frame assembly. This product is not for beginners or casual users; it requires mechanical aptitude, patience, and proper tools beyond what is included in the jig kit.

Shipping & FFL

Because the polymer80 pf9ss 80% single-stack frame and jig kit (glock 43 compatible) is an unfinished 80% frame, it is not classified as a firearm under federal law. It can be shipped directly to your residential or business address without an FFL transfer. No background check is required for purchase. However, once you complete the frame by machining the required cavities and installing the fire control components, you must comply with all federal, state, and local laws regarding firearm possession and serialization. Some states and municipalities have specific regulations concerning unfinished frames; it is your responsibility to verify legality before ordering. We do not ship to states or localities where 80% frames are prohibited. By purchasing this kit, you acknowledge that you are not prohibited from owning firearms under federal law and that you will complete the build in compliance with all applicable regulations.
