Polymer 80

Building your own handgun at home is a great alternative to just buying a Glock® and paying extra at the gun store. Picking up one of these polymer 80% frame and jig kits is the way to do it! The ATF says it’s legal, with no paperwork required (just check your local and state laws, too). The best part? These 80% frames and kits are all compatible with the corresponding Glock® Gen 3 handgun parts, including magazines.

What’s Included

Each kit includes a Polymer80 pistol frame, a disposable jig, a proprietary locking block, and milling and drilling blocks – everything you need to complete the frame blank, minus a handheld drill and tools. We carry a full selection of Polymer 80 pistol frames, giving you the freedom to pick virtually any configuration and caliber.

Glock® Compatibility

Some of our favorite kits are the Polymer80 PF940C ™ 80% Compact Pistol Frame and Jig Kit and the PF940v2™ 80% Standard Pistol Frame Kit. The PF940C™ kit is compatible with the Glock® Gen3 G19/23 (3-Pin) and includes the Jig. The PF940v2™ is compatible with the Glock® 17/34 and includes a jig as well.

No Experienced Required to Build

The best part about building your own handgun with a frame blank is that it requires few tools and very little equipment to complete. Polymer is easy to cut and drill with basic tools, and the entire project should take less than 2 hours, even for first-timers! Once your frame blank is completed, simply assemble it with the appropriate factory Glock® parts or aftermarket kits, and you’re ready to hit the range.
