NOTICE:  On March 19, 2023, Polymer80 was granted a preliminary injunction and a restraining order against the ATF. Because Gunbuilders is an entity that buys directly from Polymer80, we are able to resume selling Polymer80's products to our customers.  

What is a P80 Frame?

P80 frames, also known as Polymer 80 frames, are firearm frames manufactured by Polymer80.

These frames are designed as 80% complete, meaning they are partially finished and require additional machining and assembly by the end-user to become functional firearms.

P80 frames are commonly associated with Glock® pistols and are made from polymer materials. They are designed to be compatible with specific Glock® models, such as the Glock 17, Glock 19, or Glock 26, among others. These P80 Glock compatible frames offer several advantages, including weight reduction, customization options, and potentially lower costs compared to purchasing fully assembled firearms.

Polymer80 has improved the original "brick" design of the Glock® with many ergonomic upgrades too. The P80 frame's got a more aggressive grip texture for a more positive interaction with the surface of your hand. It's got both an extended beavertail and a double undercut trigger guard, so you can really get your grip high on the frame for more control, less felt recoil, and faster follow-up shots. It's also got ledges on the sides for indexing with your thumb, so you can find the same solid grip every single time.

  • PF940C is compatible with Glock 19, G23, and G32 handguns.
  • PF940v2 is compatible with Glock 17, G22, G24, G31, G34, and G35 handguns.
  • PF940SC is compatible with Glock 26, and G27 handguns.
  • PF9SS is compatible with Glock 43 handguns.
  • PF45 is compatible with Glock 20, G21 handguns.

Completing each frame or receiver requires drilling a few holes and removing excess polymer material using the included bits. These steps can be completed with basic hand tools (all you need is a vise, a Dremel, and some files). Little to no experience is required, thanks to easy-to-follow instructions! Once completed, simply pair your pistol frame with the appropriate Gen 3 Glock® barrel, slide, and parts kits, and hit the range in a single day.

What is an 80% Frame?

Like an 80% lower, an 80% frame is an unfinished blank that functions as the firearm component of an assembled handgun once fabricated. And, like an 80% lower, the frame blank requires some basic cutting and drilling operations to make it ready for assembly. 80% frames are available for the GLOCK and 1911 platforms.

P80 Frames: Serialization & State Restrictions

Some states require serialization of your P80 frame before fabrication. Other states have banned 80% frames, certain firearm parts, and other products we sell. Check your local and state laws, and please confirm whether we can ship to your state before ordering.
