Polymer80 PF45™ 80% Full Size Frame and Jig Kit (Glock® 20/21 Compatible)

Thanks to some unwitting press lately, everyone knows or has at least heard of Polymer80. They’ve defined themselves as the industry standard for 80% pistol frames. We would like to introduce Polymer80’s PF45™ 80% pistol frame. This larger-sized frame is compatible with Glock® components for Gen 3 3-pin: 10mm and .45 acp (G20 and G21).

Finish your build with G20/G21 parts kits!

This frame features an extended beavertail and thumb ledge for better control. A double-undercut trigger guard enhances comfort, allowing for a firmer grip. Lastly, engineers upgraded the 22-degree grip angle to 18 degrees. This new angle provides better recoil control and quicker follow-up! Even with a new grip angle, the PF45™ is still compatible with OEM and aftermarket Glock® magazines.

PF940V2 80% Frame Features

• Compatible with components for 3-pin (Gen 3) G20 and G21.
