About this product
If you already own a slide or upper for Gen 3 Glock 20 and 21, the PF45 is the large 80% option that matches it. FrameCraft lists the PF45 together with the lower parts kit and pins a builder still needs after the frame is done.
What you get
- PF45 80% large frame
- Stainless front and rear rail modules
- Polymer jig
- Drill bits
- End mill
What you still need
A drill, a vise and, for AR lowers, ideally a drill press. Parts kits and slides are on the shop page sorted by frame. Slimmer grip than the factory large frame; for 10 mm and .45 ACP builds. Magazines: 13 and 15-round G20/G21 magazines.
Sold as an unfinished frame or receiver. Check your state and local law before ordering; we do not ship where unserialized frames are prohibited.
