Common Questions
What tools are needed to complete this 80% frame?
You will need a drill press or hand drill, a router or Dremel tool with a milling bit, and standard gunsmithing tools (punches, hammer, files). The included jig provides the necessary guides. Always follow the manufacturer’s instructions precisely.
Does this kit include a slide or barrel?
No. This is a frame kit only. You will need to source a Gen 3 Glock 22 or 23 slide, barrel, recoil spring assembly, and a lower parts kit (LPK) separately to complete a functional pistol.
Is the jig reusable?
The included polymer jig is designed for a single use to complete one frame. For best results and to maintain critical alignment, do not attempt to reuse it on another frame.
