Oh brownells has a good deal going on a p80 lower and their slide with RMR cut and window over the barrel. Like $275~
That’s what I’m looking into doing. I like the look of that frame compared to the stock Glock frame
No I haven’t. I’ll check that out. What material do they use?

casting plastic was a lot harder than I thought it would be. I tried making some molds and cast some marble size pieces, man it went bad. might have been the 2 part resin I bought, but everything that could go wrong did. air bubbles ,over mixing, and poor mixing. I had a sticky gummy mess, then the next try my resin hardened in the mix cup before I could pour it.
I say all that just to say it might not be as easy as it sounds. when we investment cast at work, we have a pressurized and heated wax pot (toy custom parts makers use the same but with plastic) . we also have a vacuum chamber/casting table to help get the bubbles out of our vestment and draw the liquid metal into the mold when we pour.

I know the folks that produce this
Freedom-15 100% AR-15 Lower Mold Kit, ARCast Resin & Pre-Bent Braces
They spent a lot of time on it and the brace within. I’ve seen a few poured.....and for what my opinion is worth,the finished product looked and felt beefy, but really light. I have a kit,but have not used it.
I’ve seen a well used lower of theirs as well. It looked like absolute hell but was whole.

You’d have to put a Nerf sticker on it!

I like my Poly 80, everything is Glock except for the disconector and frame.
I had a slight issue of not going into battery 100% of the time but I just had to reinstall the takedown detent spring as it was dragging on the recoil spring.
It was very simple to assemble (I’ve never been inside a Glock before building this one, and I’ve hardly shot them either) and I milked mine with a Dewalt hand drill and no vice (wouldn’t recommend that)

I built 2 P80's back around the beginning of the year. Did them with a drill and a dremel tool on my vice. Built a 19 for my brother in law with a swenson slide and barrel and a lonewolf completion kit. Then built a 17 on a lonewolf slide with a lonewolf completion kit. They were very easy to do, and my 17 took a mag or two "break in" before it started cycling reliably. They are definitely a cool project, and shouldn't take you more than a couple of hours to get together.
Now my gripes.- It's NOT a way to build a glock cheaper than you can buy one. Even buying the cheap Swenson slides from Midway doesn't come out cheaper than buying a factory glock. But if you like having ownership of your own build it's cool. It does not fit glock holsters. There are a few makers who have P80 specific holsters, but they are few and far between.
Bottom line, it's a cool project, and a way to make something your own.
