Want to build a Polymer80 Glock®-compatible pistol? You'll need the Polymer80 PF9SS Jig Kit, made for the PF9SS 80% Frame. You'll need this jig to cut and drill your 80% frame blank, making it ready for assembly with a GLOCK 43 Build Kit. Polymer80 designed the PF9SS jig kit to be easy to use. It requires only basic tools and approximately one hour of your time to fabricate your frame. The jig is made from a tough fiber-nylon composite, which allows you to use it to complete up to three frames.
