We finish the kits we sell
Every kit listed here has been through our own bench at least once. That is the whole editorial position: the notes on each product page say how the frame cut, whether the rails seated first time and what we would order alongside it. Where we have not tested something, the page says so rather than inventing a verdict.

Reader questions
Answered plainly
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.
Which Glock slides fit each Polymer80 frame?
PF940C: Gen 3 G19, G23, G32. PF940v2: Gen 3 G17, G22, G24, G31, G34, G35. PF940SC: Gen 3 G26, G27. PF9SS: G43. PF45: Gen 3 G20, G21. Gen 4 and Gen 5 slides need a conversion kit or a different frame.
Which jig do I need?
Every frame kit here includes its matching jig, drill bits and end mill. Receiver-only listings for the RL556v3 and G150 need that receiver's jig, sold on its own product page.
