Your Questions Answered
What tools do I need to complete this 80% frame?
You will need a drill press or a sturdy hand drill, a vise to secure the jig, and a rotary tool (like a Dremel) with milling bits. The included jig and drill bits guide the process, but standard workshop tools are required for the milling and drilling steps.
Does this work with aftermarket Glock slides?
Yes. The PF940Cv1 is designed to be compatible with most aftermarket and OEM Glock 19 Gen 3 slides. We recommend checking slide specifications for Gen 3 compatibility to ensure proper fitment.
Is the frame serialized?
No. This is an unfinished 80% receiver. It is not a firearm and does not have a serial number until it is completed by the end user, subject to all applicable federal, state, and local laws.
