Polymer 80 Pistol — Build Your Own Handgun

Build your own Polymer 80 pistol with frames, kits, and parts from Builder’s Pistol Supply. The Polymer80 pistol platform has revolutionized the firearms hobby by making it affordable and accessible for anyone to build their own Glock-compatible handgun at home. With an 80% frame, a complete slide, and a lower parts kit, you can have a fully functional pistol for a fraction of the cost of buying factory.

Polymer 80 pistols are compatible with standard Glock components, holsters, magazines, and accessories. Once completed, your P80 pistol functions identically to a factory Glock — same trigger pull, same manual of arms, same reliability. The only difference is that you built it yourself, giving you intimate knowledge of how every component works together.
