Who It’s For

The Polymer80 PF9SS™ 80% Single-Stack Frame and Jig Kit (Glock® 43 Compatible) is built for the experienced DIY builder who wants a compact, single-stack carry option without the paperwork of a fully finished frame. Ideal for those comfortable with basic hand tools and following step-by-step instructions. This kit is not for beginners; it requires mechanical aptitude and patience to complete the frame correctly. If you have previously assembled an AR-15 lower or another 80% pistol frame, you will find this project manageable. It is also suited for those who prefer to customize their grip texture, trigger guard shape, and overall fit before final assembly. The PF9SS™ platform is specifically designed for concealed carry enthusiasts who value slim profile and reliability.

Shipping & FFL

This Polymer80 PF9SS™ 80% Single-Stack Frame and Jig Kit (Glock® 43 Compatible) ships directly to your residential or business address within the United States. No Federal Firearms License (FFL) transfer is required for the 80% frame because it is not classified as a firearm under federal law. However, once you complete the frame by milling and drilling, it becomes a firearm and must be serialized in compliance with your state and local laws. Certain states and municipalities may have additional restrictions on 80% frames or require serialization before or after completion. It is your responsibility to verify all applicable laws in your jurisdiction before purchasing. We recommend consulting with a local FFL or legal expert if you have any questions about compliance. By purchasing this kit, you acknowledge that you are legally allowed to possess and complete this product in your area.
