Which Polymer80 frame fits the slide you own?

Every frame here is cut for Gen 3 Glock slides. Match the slide first, then the kit. Gen 4 and Gen 5 slides need a conversion kit.

The build path

Three boxes, one finished frame

Frame

Pick the frame for your slide

Use the finder above. Every kit ships with its own jig, so the frame decision is the only one that can go wrong.

Frame finder →
Finish

Drill the pins, remove the tabs

The jig guides the pin holes; the rail tabs come off with the included end mill in a hand drill, or a file. Pistol frames take an evening. AR lowers go easier on a drill press.

Build guides →
Parts

Add rails, parts kit and slide

Locking block and rear rail modules are in the kit. Lower parts kits, pin sets, slides and barrels are on the shop page, sorted by frame.

One box, everything the cutting needs

A kit here means the frame, both rail modules, the matching jig, the drill bits and the end mill together. That is the difference between a kit and a receiver-only listing, and it is the difference between finishing on a Saturday and waiting for a second parcel. Receiver-only options are listed too, for builders who already own the jig.

Straight answers

What builders ask before ordering

What is the difference between the RL556v3 and the G150?
Both are polymer AR-15 80% lowers. The RL556v3 has a solid core, flared magwell and a threadless grip design; the G150 Phoenix2 has an integrated trigger guard and a threaded, reinforced buffer tube housing. Each needs its own jig.
Does a PF940C take Glock 19 magazines?
Yes. The finished PF940C runs standard 15-round G19 magazines and larger G17 magazines. The PF940SC takes G26 10-rounders and longer magazines with a sleeve.
What tools do I need beyond the kit?
A drill or drill press, a vise, a file, safety glasses and cutting oil. The jig, drill bits and end mill are in every frame kit.
How long does shipping take?
Orders leave a US warehouse within one to two business days by tracked carrier. Frames and receivers go only to states where they are legal; parts and jigs ship everywhere in the US.
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.
