What tools are required to complete the PF45 frame?
Completion requires basic tools: a hand drill or drill press, a hobby router or Dremel tool with a router base, and standard hand tools like punches and a hammer. The included jig and drill bits guide the process, but proper workshop safety and technique are essential for a successful build.
Which slide and parts kits are compatible with this PF45 frame?
The PF45 is designed to accept Generation 3 Glock 20 (10mm) or Glock 21 (.45 ACP) slides and OEM-spec upper and lower parts kits. You must select components specifically labeled for the G20/G21 large-frame models, as parts for compact 9mm/.40 frames are not compatible.
Is this kit legal in my state, and does it require an FFL transfer?
This 80% frame kit is currently sold as a component without a serial number and does not require an FFL transfer under federal law. However, state and local laws vary dramatically. It is the purchaser’s sole responsibility to research and comply with all applicable laws regarding the purchase, completion, and possession of firearm components in their jurisdiction before ordering.
What is the primary advantage of building with a PF45 kit?
The primary advantage is unparalleled customization. Building from a PF45 kit allows you to select every component—from trigger and barrel to sights and slide—tailoring ergonomics, trigger pull, and aesthetics to your exact preferences. It also provides deep mechanical understanding of your firearm, making maintenance and future upgrades straightforward.
