Build Your Own Glock With Every Part Delivered to Your Door

Is this for real?  You can legally buy every part needed to build a complete Glock?  The answer is yes.  But, you will pay a price for it.  Slides are not cheap and these days you can almost get a whole Glock for the price of a factory slide.

Just a few short months ago, Polymer 80 released their PF940C 80 percent lower Glock pistol frame.  I was browsing Instagram and everywhere I looked, these frames were popping up. With that being said, I had to see what the rage was all about so I contacted Alex from Polymer 80 and he sent me a frame to check out.

If you don’t know how these frames work, you have to complete the build yourself.  That’s what makes it legal to ship them to your house and that is why they are call Polymer “80”.  They are 80% uncompleted frames that you have to finish yourself.

When it arrived, I was a bit surprised to see that it came with all the tools needed to drill and mill the frame.  Drill bits, a jig and rear trigger housing.  The funny part is, I never used the milling drill bit provided but I did use the pin hole bits.

The upper and lower part kits were provided by Glockstore as seen in the photo below. The parts are a bit more pricey on Glockstore than other retailers but their shipping and service seems to be better than others.

Overall, the drilling and milling took me an hour and forty five minutes to complete.  Here are the tools I used, and you might be surprised!

1. Cordless drill

2. Dremmel

3. Files

4. Sandpaper

5. Shooterlube oil

I started by placing the frame into the provided jig making sure it was tightly seated. I then began to slowly nibble away at the tabs using my dremmel tool and a file.  Once I had all of the tabs and plastic removed, I used 1000 grit sandpaper to smooth the surface.  It’s important to make the slide tabs as smooth as possible for less drag and friction on the slide.  Watch below as Lenny Magil talks about how this is an important part of the build.

Once the slide tabs were filed down and I was content with how they looked, I moved on to drill the pin holes using my cordless drill.  It’s important that I tell you, I didn’t use a vise. I had the jig on my table and held firmly onto the jig with one hand and my drill in the other.  Once I drilled one side, I flipped to drill the other side. When both sides were completed, I sent the drill all the way through to make one continuous, straight hole as if acting like I was pushing a pin through.

I then assembled the lower parts and began fitting the pins.  The pins do run tight, but they will go in if you man handle it a bit.  I used a hammer and placed the frame on a folded towel for cushion.  Some say to use a hole punch to widen the holes a bit.  I didn’t have a hole punch handy so what I did was run my drill bits completely through one more time and that did the trick.  It took off just a tad bit more plastic and that was all it took to get those stubborn pins in place.

Now that all the lower parts are on, it was time to put the slide on and see how it reacted.  I slipped it on and to my surprise, it fit like a glove.  I was expecting a tight fit or bumping parts but no, it was a great success.

My overall thoughts?  I enjoyed building the frame and it was a lot of fun!  I’ve now built two and haven’t had any real big issues that I couldn’t easily fix.  For example, I had to buff the ejector and take the paint off.  All I did was drop some Shooter lube on a patch of 1000 grit sand paper then place the ejector face down and began rotating in a circular motion until it had a smooth almost mirror finish.  The frame texture feels good in the hand and isn’t too aggressive.

The project isn’t exactly cheap, but if you want a fun project for a rainy day or something to do with your son or daughter, this is a great project and I would recommend it!

    1. Hey Chris. You can get all the parts at around $700. Like I said, a bit pricey but fun.

      1. 700!? Sounds like a lot of fun but dang.

        1. Depending on where you buy parts it can be cheaper. Midway has parts pretty cheap. If I looked hard enough I could probably scratch it together for closer to $550.
