Who It’s For

This kit is intended for individuals who possess the technical skills, tools, and patience to complete a firearm frame from an 80% state. It is ideal for hobbyists who want to customize their grip angle, trigger reach, and overall ergonomics without purchasing a complete pistol. The polymer80 pf9ss 80% single-stack frame and jig kit (glock 43 compatible) is also well-suited for those who prefer to build their carry weapon to exact personal specifications, including installation of aftermarket triggers, extended magazine releases, or custom stippling. Builders should have experience with basic hand tools such as a drill press or Dremel, and must be comfortable following detailed instructions. This kit is not recommended for individuals unfamiliar with firearm assembly or those lacking a clean, well-lit workspace. For best results, use a drill press with a depth stop and a vise to secure the jig during machining. Note that this kit does not include a slide, barrel, or lower parts kit; these must be sourced separately.

Shipping & FFL

This product is classified as an 80% frame and is not considered a firearm under federal law. It may be shipped directly to your residence without an FFL transfer.

Some states, including but not limited to California, New York, New Jersey, Connecticut, Maryland, and Washington D.C., impose restrictions or outright bans on 80% frames. By purchasing this kit, you confirm that you are legally eligible to own firearms and that you will complete the frame in compliance with all applicable laws. Once completed, the frame becomes a firearm and must be serialized if required by your state. We strongly recommend consulting with a local attorney or FFL dealer before ordering. No returns or exchanges are accepted on modified or completed frames.
