Build Your Own Glock 43 with GlockStore’s New Single Stack 80 Percent Lower

The MSRP for the SS80 kit is $129.99.  Now, you’ll still need to buy a slide, mags, and additional parts to have an operational handgun.

Attention all Glock 43 fans!  GlockStore launched this week its new Single Stack 80 percent lower, aka the SS80, for the G43.

Sold exclusively through the GlockStore, you can place your order today for an estimated mid-March delivery.

What separates the SS80 from the factory Glock 43 are a number of features or, depending on your perspective, improvements.

For starters, the SS80 is said to have been constructed from a “more durable nylon/polymer blend” than the original.  This purportedly makes what is an eminently reliable pistol even more reliable.

Features that improve shootability include a more aggressive grip texture, a double trigger undercut, and an extended beavertail.  Together they should allow the user to get a high and firm purchase on the handgun, reducing felt recoil while improving speed and accuracy.


  • New Texture and Frame Style
  • Double Trigger Guard Undercut
  • Extended Rear Rail system
  • Extended Beaver Tail
  • And Extended Locking Block Rail System
  • Blank Serialization Panel
  • Drill bits
  • Jig fixture to guide in completion of the lower
  • SS80 window sticker

GLOCK 43 – A New 9mm Single Stack – Hands On Full Review

The SS80 from GlockStore.

Comes with a jig fixture for easy completion.  

Why build your own?  Because it’s fun.  Because it’s cheap.

Lenny Magill, who founded the GlockStore, put together a 3-part series on the SS80 build.  The first installment is below.  Aside from the kit, users will need the following tools and materials to finish the build: a drill, a Dremel tool, sandpaper, WD40, and a vise.

    used a pf9ss lower and had to hunt down the rest
    of parts online for the total of $483. dollars

    Does anyone know if they fixed the problem, or plan to fix the problem with the locking block sitting too high in the frame?

  • Robert S. April 15, 2018, 12:47 pm

    To codenamedave, you are so far off base it’s unreal! It’s perfectly legal to build this firearm in ca. Please before you give advise please know the laws !!

    Am I Figuring this right? I mean, is this kit completed going to set me back 750.00 or more BASIC?
    If that is right it seems a little criminal doesn’t it? Like buying a weapon from a dude in a trench coat at the corner Gas station.

    Sounds like a nice way to put together a off paper stash but if you gotta do that it’s time to fight. I’d like to build one just for kicks.

    • Mike March 4, 2018, 4:35 pm

      that’s what I was thinking, it’s a little expensive though to be just for kicks, I mean as far as a 7 -8 hundred dollar chunk of plastic. LOL I mean Hobby wise, even though it’s a crazy amount more time. Maybe whittling one out from scratch would be more rewarding. LOL i mean for this price you can buy a used Mill or even a new Chinese harbor freight. Or just have a friend with the ability to print some parts out on his off time at work LOL

    This guy doesn’t blink – not even once the whole video. It is creepy

  • Joseph Dibella January 20, 2018, 6:39 pm

    Can you send the ss80 to Michigan and the complete upper. For the Glock 43 and what is the will come to my house correct

    It can’t be “California compliant” because it’s not a firearm, and it’s not “perfectly legal” to make one into a firearm in CA. It’s illegal to build your own semi-auto handgun in CA unless it’s roster compliant, which means submitting multiple samples accompanied by money to the gummint for testing and meeting all roster requirements including micro-stamping. The biggest manufacturers aren’t up to it, but if someone wants to give it a go from their garage in their spare time, have at it. The only other possible way is to build it as a dimensionally compliant single-shot break-top or bolt action, serial number & register, etc, then convert it to a semi later. I can completely understand why the author may not be knowledgeable about CA gun laws, but you know, it’s all right to shut up when you don’t know what you’re talking about.

      Firearm Manufacturers – meaning federally licensed ATF designated manufacturers are required to go through the compliance process. You as an individual are not a federally registered firearms manufacturer and are not required to go through the CA compliance process.
      It is legal for — an INDIVIDUAL – who is not a licensed manufacturer to build a firearm for personal use. They cannot build them for sale or transfer to others.
      The ATF has officially ruled on this and it is legal. You don’t think a guy that built a multi-million dollar business and has never been in trouble with the ATF didn’t consult with his legal team and require written correspondence from the ATF certifying the legality of the process by them after examining the process themselves before investing millions and risking his company, family and freedom?
      He IS a licensed firearms manufacturer, I don’t know which class as there are several but he has his licenses posted as required. Had you done your homework, you wouldn’t have said what you did. Try it next time.

    Only way its cheaper is if you get lucky and its on sale. A full size lower is usually $150, plus the internal parts, plus a slide and barrel. Midway had the full size for $50 not long ago, the internals for like $30. Yea now its cheaper. I made a brass guide rod for mine, as I had wolff springs, but no guide rod. Did not want to fork over the $25 for a rod. Had a brass rod I could spin up on the lathe.

    With my ESP powers, I can already feel the diseased state senators of Kalifornia rushing for their pens to make building a firearm a state felony.

    • Bob January 17, 2018, 5:02 pm

      How is it cheaper or is there another way to go? New 43’s can be had for $400-$450. The upper thru GS is $400…..

      • Dustin January 19, 2018, 4:06 am

        Not everything is about being a Cheap Charlie. Some things are worth extra. This is one of them.

        My Hummer costs more than a Civic. And it’s worth every penny.

        • WarZone January 19, 2018, 11:10 am

          Your hummer is the worst quality American vehicle since the Pacer.

        • Mad Dog January 19, 2018, 2:25 pm

          Bob’s comment I believe is due to the article saying it’s cheap. It’s not cheaper than just buying a G43. The cheapest I’ve been able to put together for all the parts is $583. The $400 complete upper from GlockStore is the cheapest way I could find to get all the parts for the upper. Not saying I won’t do this because it’s fun and easy but it’s definitely not the cheapest way to get a G43…

      • Scotty Gunn October 5, 2018, 6:50 pm

        It isn’t cheaper. I got my G43 used for 300. Love it, can’t build one for that. Give it a year or two and people will start to make lots of aftermarket stuff for the 43, like slides,etc. Then it will drop a little bit.

    • Mark N. January 20, 2018, 12:38 am

      They did not do that, but as of 1/1/18, they did require that you obtain a serial number from the California DOJ (with back ground check), and engrave that unique serial number on the frame (to the same spec as that in the federal regs for firearms manufacturers) BEFORE starting the build. I don’t recall the cost, but I assume it is at least $25, maybe $50, plus the cost of engraving. I also assume that you have to have a California Firearms Safety Certificate ($25, good for five years), but I don’t think any one has asked that question yet. I haven’t checked because I am not going to build one. With the regs and additional costs, it is too expensive.And I am not a Glock fan either.
