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.

Three boxes, one finished 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 →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 →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.
Parts and slides →Pick the frame, finish it once, build it right
Most 80% builds go wrong at two points: buying a frame that does not match the slide you already own, and finishing the rails without the right jig. Every kit here names the exact Gen 3 slides it accepts and ships with its own jig, bits and end mill. If you are unsure, email the slide model you have and we will confirm the frame before you pay.
