  1. Smart –

    Received my frame the other day and I’m impressed looks great can’t wait to build it.

  2. Brian S. –

    This pistol frame is really close to being perfect. The only gripe for me is the stippling on the upper portion of the grip but that is easily resolved using talon grip tape

  3. Jeremy –

    Fantastic feel , quality. Very well made best 80 out there

  4. Andrew –

    Awesome work
    Great feel to this grip and the frame looks amazing now that the work is done. Great grip angle, everyone wants to know where I got it

  5. Rocky –

    Well,it took awhile but I finally got it.The customer service is great considering how busy they are. I will buy again from this company.

  6. Christopher Q –

    Nice custom frame
    My custom job feels great feel in the hand, has a smooth light custom trigger, and many other beautiful features such as custom reduced weight slide, tungsten rod and threaded match barrel for Supreme Ultra performance. Why buy junk when you can have the best.

  7. Quan –

  9. Jeffery A –

    Everything was great. Order arrived quickly and as described

  10. Dallas N –

    The GST-9 pistol frame is magnificent. You can tell that it is quality as soon as you pick it up. I have no experience with any other brand so I may be biased. I can confidently say that I did hours of research over multiple days before deciding on 80%. Bring back the white!

  11. Jeff A –

    Great looking frame. Easy to finish.

  12. Andrew T –

    Best jig ever good quality great customer service.

    Great frame, 👍 I would buy again.

  14. Newton R –

    Great product, great quality.

  15. Walter Mayer –

    Came out beautiful. Came with a super nice metal trigger shoe instead of that cheap plastic other companies offer. Really like the abstract colors and customer service. Build was easy and my holosun looks good on it. Very accurate so far and took very little adjusting to run super super smooth. Highly recommend over p80.

  16. Thomas E –

    Love it worth the wait

  17. Caleb S –

    A very fun project

  18. Paul D –

  20. Nicholas W –

    The design and build of this frame was very impressive. I like the new improvements from the previous design.

  21. Kevin C. –

    Great build kit, straight forward with few issues.
    Will be ordering again for my next build.

  22. Eric P –

    10/10 build feel service

  23. Jonathan H. –

    Took my time. I am very meticulous. Drilled the blank. Upon the build I was having a bit of trouble with the assembly, re-visited the jig and drills. The assembly went smoothly. When I installed the slide I noticed that the frame dropped a bit at front under the accessory rail and the nose of the slide. Be patient, do not force anything.

  24. Polycap –

    This is a great jig I really like it its vary simple to use and puts out a vary nice finished product no need to try another jig I did my research and got led here over and over sure glad this is what I went with

  25. Rexy –

    I waited a while to post this. After using it 12 times on 7075 lowers with 4 different sets of hands, here’s a few helpful hints. Sometimes the trim routers will slide in their collars, resulting in too deep of cuts. Not the Jig’s issue, just something to pay attention to.

  26. Andrew Mayer –

    I have done multiple lowers. Even cleaned up and finished one I started with a (drill multiple holes) style jig. Tho cleaning up that lower led to my only issue with the end mill. 5d was right there to help diagnose the issue and sent replacement end mill right away.

  27. James S. –

    Great product, will buy again.

  28. Albert –

    Molding quality is great. Plastic composition is superb. Only minor downside is fitment of 19/17 lower grip modules.

  29. Andy –

    Wow very fast shipping I love it

  30. Tommy Moore –

    Hey guys (customers), I ordered the pro jig multi-platform, as well as the bits set and the typeC endmill on 3-31-21 and recieved it today, 4-20-21…. I was extremely anxious, but I never called 5D. Given the times we are in, EVERYTHING related, is taking forever. Haven’t used it yet but based on other jigs I’ve used this one definitely has me exRead more about review stating Give you insight on shippingcited.
    To 5D , thanks so much for getting my order to me, I’m very excited to finally use it.

  31. Charles N –

    Great service representatives! Great products…

  32. Jess C –

    Excellent product! Be sure to get OEM Gen 1-3 Glock parts, it will work the best with minor adjustments.

  33. Jeffery P –

    Love it! It turned out amazing! I will totally buy more

  34. Thomas E –

    Awesome kit.

  35. Martin –

    I have built both a Polymer 80 and a GST9 – MOD 1. I really prefer the GST9 – MOD 1. The ledges on the side of the frame fit my hands really well. The texturing feels good, not to much. It seems to be engineered very well. Overall this is an amazing system. I will be using the GST9 – MOD 1 for my future builds.

  36. John D. –

    This is my second GST 9. My dad liked the first one I built so much that I gave it to him. I liked it so much that I had to order another one. The action with just a little hand fitting is like greased glass. Thanks for making the foundation of an excellent handgun.

  37. Peter Walt –

    Love it. Has a lot of cool features u don’t get with a factory glock.

  38. Marley V –
