Last reviewed: 2026-04-30 by Prince Frederick , FFL08 holder · Forward Freedom LLC · Prince Frederick, MD — Full-build-kit specialist. The Polymer80 PF45 is an unfinished 80% pistol frame compatible with Glock 20 / 21 / 41 (Gen 3). This kit pairs the frame with the matched jig and the bits called out in the build instructions — finish the rails and trigger pocket on the bench, no separate tooling needed.
The jig kit locates every cut and drill point, so a first-time builder can finish the frame with a drill press or a steady hand drill.
Shipped fast and discreet from Texas Gun Shops in Houston, TX. Unfinished frames and receivers cannot ship to states or cities that prohibit them. Not sure about your area? Message us before you order.

Frequently asked questions
- Do I need an FFL to buy the Polymer80 PF45™ 80% Full Size Frame and Jig Kit (Glock® 20/21 Compatible)?
- No FFL is required for an unfinished 80% frame or receiver under federal law, because it is not yet a firearm. Some states and cities restrict or ban unserialized frames, and we cannot ship there. Check your local law before ordering. This is general information, not legal advice.
- Are Polymer80 frames legal in Texas?
- Texas has no state law restricting 80% frames or receivers for personal builds. Federal rules still apply, and a home-built firearm cannot be sold without proper licensing. Laws change, so confirm the current rule before you build.
- What do I need to finish the Polymer80 PF45™ 80% Full Size Frame and Jig Kit (Glock® 20/21 Compatible)?
- Everything to locate and make the cuts is in the box; add a drill press or router and a vise. Each product page names the frame family it fits. Email us your model if you are unsure and we will confirm before you pay.
- Is this in stock and how fast does it ship?
- Yes. It ships from Houston, TX within one to two business days, tracked and in plain packaging.
