What Buyers Ask
How is the quality of the anodized finish?
The finish quality on our current batch is excellent. Our staff noted no visible tooling marks, and the anodizing is even and consistent across the frame.
What parts kit do I need for this frame?
This frame is compatible with standard Gen 3 Glock 21 parts kits. You will also need a PF45-specific jig and drill bits to complete the frame, along with a slide and barrel.
Is this a complete firearm?
No. This is an unfinished firearm frame, often referred to as an 80% frame. It requires machining (drilling and milling) to become a functional firearm receiver, which must be performed in compliance with all federal, state, and local laws.
