Polymer80 PF45 80% Full Size Frame and Jig Kit (Glock 20/21 Compatible)

Overview

The Polymer80 PF45 80% Full Size Frame and Jig Kit (Glock 20/21 Compatible) allows you to build a complete, full-size pistol frame from an unfinished polymer blank. Designed for Glock 20 and Glock 21 components, this kit provides the structural foundation for a .45 ACP or 10mm build. The PF45 frame is machined to 80% completion, requiring you to finish the remaining material to accept a standard Glock parts kit. Each kit includes the frame, jig, and necessary tooling to complete the project at your workbench. This is a legal, non-serialized frame component that complies with all federal regulations when assembled for personal use.

Shipping and FFL

This polymer80 pf45 80% full size frame and jig kit (glock 20/21 compatible) ships directly to your home address. Because it is an 80% frame — not a complete firearm — it does not require transfer through a Federal Firearms License (FFL) dealer. No background check is needed for purchase. However, once you complete the frame by drilling the pin holes and milling the pocket, the resulting firearm must comply with all applicable federal, state, and local laws. You may be required to serialize the completed frame depending on your jurisdiction. Check your state and local regulations before purchasing. We do not ship to states or localities where 80% frames are restricted or prohibited. By purchasing this kit, you confirm that you are legally allowed to own and manufacture a firearm for personal use in your area. If you have questions about compliance, consult a qualified attorney or your local law enforcement agency.
