Polymer80 Glock style handguns

Postby Flowmaster » Wed Nov 06, 2019 11:27 pm

Anybody have any experience with Polymer80 Glock-style handguns? I started a thread on here in April of 2018 about 80% handguns, but that was a while back. I've learned some about them since the last thread.

Polymer80 Glock style builds are really popular at the gun shows in my area. Its common to see 2 or 3 dealers set up at shows selling the frames and associated parts. That's sort of started a price war among companies and that's great for the consumer. At a recent large gun show (over 1,200 tables), one of the dealers was selling complete kits for $400 out the door. That included the 80% frame with jig/bits, used Glock 22 magazine, used lower parts, and a used Glock 22 complete slide with barrel and recoil spring. That's cheap.

For those who may not be familiar, Polymer 80 makes 4 frame sizes. There is a full size (for Glock 17 and Glock 22 builds), a compact (for Glock 19 and Glock 23 builds) and a compact size (for Glock 26 and 27 builds). There is also a CL frame which uses the compact size grip frame and the standard full size slide so people can put a 17 size full size slide on a 19 size grip. The frames with the jig, drill bits, and rails goes for $120-150 online.

The kits are easy to complete just from watching some youtube videos. The frame comes with a one time use plastic jig with the drill bits needed. Basically drill the 3 holes, cut off some plastic tabs, and you're ready to slide in the included metal frame rails. Then pin those in place while you're installing your frame parts like the trigger and ejector housing, then you're most of the way there. The full size and compact frames take Gen 3 Glock slides.

These 80% Glock style builds are so popular now that there are a lot of companies out there making aftermarket slides. You can build one using all new parts that don't say Glock on them anywhere. Its kind of neat that some companies like Brownells even has their own line of aftermarket Glock slides. I'd guess that the people completing 80% builds would be a big reason there is enough demand to warrant producing aftermarket slides.

The subcompact frames can take Gen 4 Glock 26 and 27 parts, but the others take Gen 3 parts. Some dealers are buying up old police turn in Glocks, taking them apart, and selling the slides and associated parts along with a Polymer 80 frame as a do-it-yourself complete kit. Then the dealer is left with extra magazines, the Glock box, and the frames which by themselves always sell for at least $50 a throw on gunbroker.

If you're making it for yourself and you're never selling it, you can make one legally in most states. Some places like New Jersey have completely banned them while places like California need to have them serialized. Otherwise, you can make your own ghost gun at your kitchen table in an hour or two using files, a hammer/punch, cheap electric drill, and even a Dremel tool if you want to get fancy. Some people are getting away using tile nippers and a sharp knife instead of files.

There is money to be made there, but it's something that could easily be legislated out of existence overnight. Some companies like rockeybrass, Brownells, and 80pbuilder are riding that gravy train for as long as it lasts though.

There is a somewhat newcomer to the industry, making an 80% Glock 43 frame. It's made by SS80 which is a division of Glockstore. It takes Glock 43 parts. Same sort of deal with the jig and drilling holes, removing some material, inserting the rails, but it's different in the fact that their ATF determination letter states that the frame and the jig must be sold separately and not packaged together.
