You could make one. Legal in most states.
Buy Polymer80 PF940V2 kit
https://jsdsupply.com/shop/polymer-80-pf940v2/This is a 9mm, full sized frame.
If you don't own a power drill, buy one.
You should have a drill...Follow instructions to finish the frame. Even though the YT vid is down, go off the pictures under it. Its easy as forget. You want a hand file or a dremel, but theres other ways of grinding off material.
Buy Glock slide. The PF940V2 is a gen 3 Glock 17, so make sure every Glock part you buy is compatible. Make sure to buy a barrel, internal upper parts, recoil spring and sights. Rock Slide is very cheap but will get the job done. If you buy the slide from this website with the "internal upper parts" option checked, which you should, it will come preassembled. This saves a lot of hassle as you need a specific tool to install some parts. You can also buy mags here, if you need them.
Buy a lower parts kit. It's hard to forget this up. Many websites offer them including Ebay. JUST MAKE SURE its a gen 3, Glock 17 parts kit.
This specific website is pricey but this is just an example.Heres how to install the lower parts kit into the pistol frame.Now, assuming you have a completed frame and slide, you can now oil up the gun and attach the slide. It literally slides on from the front. Keep racking the slide while you're watching TV or something to try and "break it in", in a way. Take it to the range next day and test fire it. Comply with local and federal laws, or don't. I don't care. You're a free man.
