Polymer 80 S150 frames shipping in early April

The Nevada based company that produces mostly 80 percent finished AR lowers, will be soon be shipping out their 80 percent Glock frames in early April. According to this latest press release/update, the initial shipping will begin on April 6th, and they will be shipped out by placement of order. Apparently the company wasn’t satisfied with the look of their picatinny rail, so they are going back to make a few slight changes to the design of the rail, and that is what is causing the most recent delay in the shipment. Earlier on TFB we blogged that they would be shipping in January of this year, however that was in November of last year, and the company seemed to have pushed their shipment date up by four months. They are available for sale at this link, currently on a pre sale going at $135.99 as opposed to the post opening price of $179.99.

We have now completed the initial testing of what we consider the final prototype of the S150 80% Polymer Pistol Frame. The good news is that it works great and is fairly easy to mill with a drill press.  We have completed all of our test frames and have experienced no siginificant problems.  Unfortunately during the test-firing, it was revealed that a final adjustment to the elevation is needed, which requires an adjustment on the injection mold at the Picatinny rail section. This change requires 10 additional business days to complete, per our manufacturer.

Bottom Line:  Due to the changes to the mold, our timeline will have to shift to the first full week of April, with the first day of shipping on Wed April 6th.  The change on the Picatinny rail is unavoidable; we have attempted to avoid making the adjustments in order to be on target for production.  However, we know our customers will be even more dissatisfied with a flawed final product than having to wait a couple weeks longer to receive their orders.

To recap for those readers who might have missed the previous article, the S150 frame comes to you as an 80 percent finished product, with you having to mill out the barrel bridge, top rails of the reciever, and the slide guide rails. Once this is completed, you are then supposed to install all the metal components that come with a standard Glock frame, such as the trigger group, magazine catch, etc… and you put a standard Glock slide/barrel/recoil spring on the frame, and you then have a functioning Glock like handgun. 80 percent lowers exist  for the 1911 platform, but this will be the first time a design is put to market for the Glock platform. All the tools necessary to complete this production are included with the product.

    This has me all hot & bothered. When I have an hour to spare I’ll probably price out what the rest of components would cost to fully outfit the weapon to a “stock” (or thereabouts, nothing too fancy) G19.

    • JumpIf NotZero

      It’ll cost almost as much as a new Glock and almost certainly more than a good deal on a used one. Absolutely more than a police trade-in. It’s usually more cost effective to buy a whole gun than just an “upper”.

      But… This has the appeal like anonymoose implied that you can get a frame to mess with at lower cost.

      • ExMachina1

        True only if you buy stock Glock parts. But if you instead add in some upgraded internals, a Lone Wolf barrel and LW slide, you will have a primo gun for much less $$.

        My only criticism is that they started on a G17. If it was a G19 I would have already bought one (maybe two)

  • BattleshipGrey

    $135 seems like a pretty good sale price, which must be saying something since I’m always complaining of pricing here. Other than the pic. rail, this product doesn’t really appeal that much to me since I happen to like stock Glock frames.

    • Budogunner

      Especially if that price includes necessary tools.

  • Anonymoose

    If I got one of these I’d probably do a grip-reduction on it.

    • JumpIf NotZero

      I did that to my 17. Love/Hate relationship with it.

      • Bart

        What’s your experiences in the “hate” department with the grip reduction? Not trolling, serious question..

        • JumpIf NotZero

          Serious answer… I don’t know!

          I just struggle with shooting it as well as other guns. I think my grip became too small for my hand, it’s an amazing job the guy did but… I think it’s just overall too small.

          If I “give up the gun” at all even a little bit, I’m low and left like a new shooter. If I rush it opens up fast. It seems exceptionally difficult to get a straight back trigger pull with my gun.

          I really am just starting to think I went too small overall. Hump removed, stippled, grip reduction. It’s definitely a smaller handgun than a PPQ with the small backstrap. Not sure what to do about it…. I’m burning about 400-500 rounds a weekend and I am getting my game back, but it just seems a lot less reliable compared to where I am with other handguns.

          Now, if I get mad and force that bullet on target (solid follow through, not giving up the gun, no hesitation on the trigger pull), it’s awesome. I might switch back to a fullsize 17 frame for awhile and see how I feel about that. Maybe I sell this one and do a new 17 cut to 19, but not mess with the stippling or hump reduction so much.

  • Phillip Shen

    I applaud this company’s approach, and this gives us hapless gun owners in California some hope for the future. See in CA, we have a de-facto ban on new handguns thanks to a requirement of any new guns to be “microstamped” to be on our approved-gun roster. That’s why we have no new gen 4 glocks, etc for the general public.

    There is nothing in the law (so far) about building your own firearm from an 80% lower, so this kind of approach gives us reasons to be happy. Maybe in the future 80% arms will do gen 4 frames in the future, or other manufacturers as well.

    • JumpIf NotZero

      There is nothing in the law (so far)

      Oh, don’t worry. They’ll fix that “loop-hole” for you soon enough. You’re free to move though!

      • Budogunner

        Your only free to move while there is someplace Free to move to. Infringement upbeat Constitutional rights should not be tolerated in any State. That is the true purpose of a federal government, too ensure we are all equally free.

  • JumpIf NotZero

    Ghost-Handgun…. 90% of the appeal would be to just have.

      You’ll lose it easily due to its ghostly nature 😛

  • JumpIf NotZero

    That second video is literally 1/3rd logos :

  • Edeco

    Hmmm, I do happen to have a bunch of extra glock guts due to reasons…

  • iksnilol

    So basically a Glock with a comfy grip and an actually competitive price (during the pre-sale)? Nice.

  • Rog Uinta

    I was interested in this until I realized the rear frame rails are polymer.

    That’s right. The slide rides on polymer rails.

    Think that one over for a bit.

    • SGT Fish

      it is surprising they didn’t make a bolt in stamped sheetmetal insert for it. especially when guys were welding up sheetmetal glock frames before.

    • JoelC

      A lot of Kahrs have rear polymer rails. They are still pretty reliable. Most of the stress is on the front rail.

      • Squirreltakular

        Yup. Having a Kahr, this doesn’t bother me.

    • Kelly Jackson

      On the rear, on the front there’s a metal “Locking block” that also happens to have metal rails built into it

    • Squirreltakular

      From the press releases they put out last year, they made it sound like there would be an included chunk of metal that needed to be installed to become the front rails.

    • Gregory Markle

      Ruger uses rear polymer rails as does Kahr, never heard of it being an issue with either of them.

  • I’ll get one when they have a 80% frame in 26/27 size for the .22LR conversion slide and barrel I have for it.

  • Kelly Jackson

    I get that the “locking block” has the metal rails for the front half of the slide to ride on, are there no metal rails in the rear?

  • JoelC

    I wonder if this can be trimmed down to G19 size. I guess I’ve never really compared the fronts of the 2 before…

    • They gave a g19 size in the works.

      • Machining costs are high for the “low volume” they’re doing. And actually, the cnc’inh mold : expensive, but the hand deburring and polishing is just as expensive, if not more.

  • me ohmy

    …and don’t forget..if you mess the process up.. they will replace the fragged frame for a new one

  • Cal S.

    Just pair with a Mech Tech ccu and you’ll have a ghost rifle.

  • Drunk Possum

    I said it on another blog, I’ll say it here:
    The ONLY reason I’d be interested in this is to piss off the hoplophobes. I’m not a big fan of Glocks, but I really like making the libs pee in their little huggies.

    As an aside, if they had an option for a magwell, I’d be a lot more interested in it for a competition platform.

    I foresee an upsurge in Irish democracy in the DPRK. (Democratic Peoples Republic of Kalifornia)

  • Reef Blastbody

    Would be interesting to put this and the Timberwolf aftermarket frame to the pepsi challenge. Take a G17 upper, and let a bunch of shooters switch off between the two.

  • tincankilla

    This is one big question that remains unaddressed by Polymer80, AFAIK. I think there’s also a 6″ barrel requirement in CA, too. The Polymer80 guys really do stick by their products and take the time to do it right, but they could do more to address the legal aspects in a FAQ or a legal advisory letter.

    i saw some advice on calguns to create an effective bolt action (manual cycle only) by using a 6″ barrel and a fixed, single shot magazine that locks the slide back every shot. the user would have to manually insert a bullet and close the bolt by hand.
