Polymer 80 is getting ready to start shipping their new no-FFL required model S150 80 percent complete polymer pistol frames next month.

For those who already have a “ghost gun” and are looking for that ghost glock, the S150 shown in the video above uses a standard Glock 9mm slide/barrel and lower parts kit. Just add the lower that you complete yourself and you have a functional semi-auto. They also tried it with a .40 cal version with G22 slide and barrel.

The S150 kit retails for $179 but is on sale currently for $135.99 and includes the 80 percent frame, a polymer jog, drill and end-mill bits and a locking block. When you keep in mind that you can pick up an LPK for about $60 and a loaded slide for $200-ish, you can be in biz with your homebuild polymer for about $400, which isn’t all that much cheaper than the real thing– but that’s not really the point now is it?
