PF940C Compact 80% Frame and Jig Kit for Glock 19 / 23 PF940C Compact 80% Frame and Jig Kit for Glock 19 / 23$127.80

Everything for the build in one order

The most common reason a Polymer80 build stalls is one missing part: the wrong locking block, a slide cut for a different generation, a lower parts kit that never arrived. Polymer80 Builds sells kits that are matched before they ship, lists the exact slide every frame takes, and keeps the factory pistols and rifles alongside for anyone who wants one finished.

Questions

Before you order

Do firearms ship to my house?
No. Handguns, rifles and shotguns ship to a licensed FFL dealer you choose, where you complete the background check and any state waiting period. Unfinished frames, lowers, parts and accessories ship to your door, except to states that restrict them.
Can I return a frame I have started?
No. Unused, unopened kits can be returned within 30 days. A frame or receiver that has been drilled or cut cannot be returned.
Is the PF9SS the same as the PF940SC?
No. The PF9SS is a single-stack frame for Glock 43 slides and 6-round magazines. The PF940SC is a double-stack subcompact for Glock 26 and 27 slides.
Do you ship to California?
We do not ship unfinished frames or receivers to states, cities or counties that prohibit them. Jigs, slides and parts ship everywhere in the US. Check current law where you live before ordering.
Do I need an FFL to buy an 80% frame or lower?
An unfinished frame or receiver is not a firearm under federal law, so it ships to your door in most states. Several states and cities restrict or ban unserialized frames. Check your local law before ordering; we cannot ship where they are prohibited. This is general information, not legal advice.
