GLOCK® Compatible 80% Frame

GLOCK® Compatible 80% Frame

80 percent frames compatible with most Gen3 Glock® series handguns.

Buying a custom Glock® can cost a premium, and buying a retail pistol off the local gun store shelf usually means sacrificing features, or buying a configuration you'll wind up changing later. The third option is simply building your own handgun from the ground up -- no FFL required, no paperwork, no extra fees, no special taxes.

What is a Glock®-Compatible 80% Frame?

Exactly what it sounds like: An incomplete (thus the "80%") firearm frame that's compatible with Glock® handgun parts once fabricated and made functional. Because the frame is incomplete, it isn't considered a firearm under federal law. The ATF approves of such units, and does not regulate their sale or ownership. This in-depth guide covers the topic (although it focuses on AR-15 receivers, the same rules apply for 80% frames). It is perfectly legal to build a gun at home for personal use without having to have a license, or having to submit to a background check through an FFL. Some states have banned 80% firearms and gun-making kits, so check the Shipping & Return Policy page before ordering to make sure your state isn't restricted.

80% Frame & Glock® Compatibility

Each P80 frame is designed to work with specific Glock® Gen3 handguns. Just as the Austrian gun maker uses one frame for producing its various models, Polymer80's and the SS80 frames do the same:

  • PF940C is compatible with Glock 19, G23, and G32 handguns.
  • PF940v2 and SS80 are compatible with Glock 17, G22, G24, G31, G34, and G35 handguns.
  • PF940SC is compatible with Glock 26, and G27 handguns.

 What's Included With Each Frame

Each Polymer80 frame includes a finishing jig, a machining device that utilizes hand tools to cut and drill the frame, making it a functional firearm. The jig captures the frame inside and provides you with drill bits to drill the pin holes with a handheld electric drill for installing the trigger assembly and internals. It also provides guides for cutting the frame rails and barrel seat, which is accomplished using a simple Dremel. Also included is a stainless steel locking block rail system and rear rail module for installing the trigger mechanism, barrel, and slide.

Because of ATF determinations, the SS80 frame must be sold separately from its jig and tool bits. You can purchase the SS80 jig here, which provides the same components (bits, a locking block rail, and rear module) as a Polymer80 kit.

State Laws May Vary

Contrary to federal law, some states have either restricted or banned the sale, transfer, and ownership of 80% lowers, firearm blanks, and other gun parts. Because of these restrictions, we cannot ship our products to certain states. Please confirm whether your state is restricted on our Shipping & Return Policy before placing an order. We cannot fulfill orders to restricted states if placed.
