Frequently Asked Questions

Q: What tools are required to complete this PF940C frame?

A: You will need a reliable drill press or hand drill, a vise, quality drill bits (specific sizes), and end mill bits or a Dremel tool with router base to remove the polymer tabs and channel liner area. A set of armorers punches and gunsmithing blocks is highly recommended. The process requires precision and patience.

Q: Is the blank serialization plate removable or permanent?

A: The provided metal serialization plate is designed to be permanently epoxied into the frame’s cavity once you are ready to serialize your firearm, if required by your local jurisdiction. It is not intended to be swapped out.

Q: Can I use a Glock 19 Gen4 slide on this Gen3 PF940C frame?

A: No. The recoil spring assembly and dual recoil spring guide rods of Gen4/Gen5 slides are not compatible with the single recoil spring channel of the Gen3-spec PF940C frame. You must use Gen3-pattern slides and barrels.

Q: Why doesn’t this include a jig like other Polymer80 kits?

A: This listing is for the bare frame only, intended for builders who may already own the proper jig or prefer to source specialized tooling separately. It is offered this way to provide flexibility and value to experienced enthusiasts who have completed builds before.
