— Pending U.S Legislation seeks to effectively outlaw the building of 80% Lowers. For more information, click HERE to read the proposed bill. —

PLEASE NOTE: We can no longer ship 80% Lowers to California, Connecticut, New Jersey, Washington State, New York State, or Hawaii. 

The SS80 80% Lower is sold as a separate item. To complete the lower you will also need the purchase the SS80 Builders Tool Set found here.

Here's the brand new 80% Lower that you've been waiting for… the build-your-own Single Stack 80% Lower that you complete with Glock 43 parts.

The NEW SS80 Single Stack 80% Lower is now the best 80% lower on the market. This new version is not only new but improved in design and materials!

Based on the customer feedback and months of research and development, the SS80 is made with a much stronger and more durable nylon/polymer blend that is similar to the original 43 but actually dampens felt recoil and provides even better reliability.

You'll notice the grip texture immediately. It provides a rock solid grip that feels good and is strikingly attractive. The frame is shaped with a double trigger undercut that allows you to get a higher grip on the gun, which reduces felt recoil and improves speed and accuracy.

As with all 80% Lowers, at this time there is no serial number, however a serial plate is embedded in the polymer to allow you to serialize it once completed.

The SS80 is compatible with parts designed for the Glock 43.

Also Note: For your convenience, the SS80 Builder's Tool Set now comes with a pre-drilled Locking Block. The product shown in the video is an earlier version that required additional drilling, however you can skip this step with current and future versions of the SS80 Locking Block.

Nice fun little gun


Just got my SS80 in the mail today. Quite different to build than the previous polymer 80s. The entire process is different, so it took me longer to build because I had to learn this process from scratch. I had mine together or partially together 3 times and had to take it back apart, because the SS80 requires assembly in a certain order to complete all of the steps of the build. Nice gun, fun build, but be prepared for a little different process than the polymer 80.

Worth the wait!


I was part of the original pre-order, and received mine yesterday. I am pleased with the high quality of the frame, and the grip texture is much better than on an OEM G43. I filed a bit too much on the deny rails, so the deck isn't as flush as it should be, but that's on me.

The only reason I gave it 4/5, is because of having to drill the holes in the locking block. I think that there is more of a chance of having an issue this way, than just having to drill the trigger pin holes. You really should have a drill press if you are going to drill through the locking block as well. Using a hand drill is more likely to result in holes that aren't clean.

Glockstore you nailed the SS80!


This was quite the journey with the GlockStore! I have to say this SS80 is not only more solid feeling then my original Glock 43 but the rail system provides lends to more confidence in it as a ‘shooter’. If your on the fence about this one...PULL THE TRIGGER AND BUY IT! You won’t be disappointed.

Absolutely love it.


I’ve had mine for just under a week and finally got to building it today, it was a fun experience for sure. I didn’t run into any trouble and took me about 2 hrs from start to finish. Also, excellent thing on Lenny’s part for posting the extremely detailed and helpful SS80 build videos. I would surely buy this product again. I can’t express how excited I am to take it to the range this weekend. Just know that the tlr-6 STREAMLIGHT will not work with this frame out of the box. I was able to fit mine with a simple mod. I absolutely love it and it was surely worth the wait. Thanks GLOCKSTORE.

Amazing 80% frame! Don't worry so much about drilling the locking block.


I had done 4 Polymer80 kits before receiving this thing, and I really liked how easy it was to catch on to the SS80 kit as I was able to use some of the tricks I taught myself doing Polymer80 kits to put this together smoothly.

The quality of the SS80 is excellent. It looks great, is incredibly comfortable, and is just practical without any unnecessary flashy aesthetics.

I was honestly quite nervous about drilling the locking block hole. I did it with a cordless drill that probably had less RPM's than it should have, which required me to use more arm force to press into the steel and caused some fatigue in my drilling arm which made my arm rather shaky at one point, but despite the shaky arm the locking block hole to my relief came out perfect. Those of you who are worried I would say probably don't need to worry nearly as much. Just take your time, use an adequately powered drill, and clamp the jig in a vice.

My favorite gun


I just put my SS80 together and got her out for a test run. This little thing is amazing! Shoots like a dream and feels way easier to handle than the factory 43 that I tried as a rental. To say that I'm satisfied is an understatement. I'll probably order one more, just to have as a spare in case the unthinkable happens and I somehow lose possession of the first one. Thank you Glockstore for bringing this beauty to the market.

This is a super product, have patience and it'll turn out gr8


Great product, follow Lenny's instructions and you won't go wrong. Yes you have to drill the locking block, nbd use a vise or clamp it to a table just don't smoke the bit or melt the plastic. Go slow... Make sure you watch Lenny's videos for assembly procedures it's a lil different than a poly80 g17/22 or g19/23 because you gotta drill the locking block, remove it after you drill it, install ur trigger group and slide release then reinstall ur locking block, again nbd.

Glad I waited!


I was one of the original pre-orders and was on the fence several times to get the refund. I’m glad I stuck it out! I had the complete upper and trigger kit so when my ss80 came in the mail I couldn’t wait to build it. The next day I put Lenny’s video on and it took me about 45 minutes start to finish to complete. I did use a drill press an had no issues with the build. It feels a bit rough but probably just needs a few hundred rounds put through it to break it in. I can’t wait to get to the range!

Glock 43


Got mine last Wednesday it’s my third build it literally fell together best build yet worth the wait



Just got it today! Absolutely love it! Thank you very much for making an 80% G43 lower, it feels better and stronger than the OEM G43. Can't wait to get it completed

Better than a Glock!!!


SS80 arrived today! Everything fit perfectly! Locking block was not so fun to drill, and not so fun to remove after drilling. but worth the perfect alignment. I did not use a vice (dont have one). And screws provided were not long enough to hold jig, so i had to be a little creative. Fits my Shmedium hand like a custom grip. High quality plastic, all in all will be buying another, possibly in grey.

Fastest build ever excellent results incredible grip


One problem the screws for the jig to shirt didn’t work but fastest build I have ever done Drilling locking block was very easy I suggest drill the frame first then I steer locking block a few drops of oil and drill then the other side. Came out perfect. Didn’t need a deemed or vise just a file used an small impact gun with chuck so wound not over torque. From start to professional finish 30 mins

Fun build


I got my SS80 today. Didn't take long to build nor was it difficult to drill the locking block holes. All around fun build. Will take it to the range this weekend to put it thru its paces. Only issue I had was the jig screws were too short to catch the bolts. Everyrhing else was a breeze. I gave it 4 stars because I haven't shot it and the screw issue.

Definitely worth the wait.


The ss80 is the easiest lower to complete on the market.
But be aware it is not advised to cut or trim this lower because it may crack. A knife scoring the cut or a sanding device is highly recommended.
The locking block needs to be pressed in to get a nice solid hole drilled. Used knipex pliers to seat the block, and a c clamp to hold down securely while drilling both sides, came out fantastic.
Will surely purchase an fde version.

Great craftsmanship


Great stuff awesome service GlockStore has done a great lower outstanding craftsmanship



After 4 P80 builds this is my favorite. Finishing the 20% is great except for drilling the locking block holes, it takes some time to drill. The trigger pin did fit very tight. I think it would have been just fine if it had pre-drilled holes in the locking block. After almost 300 rds. it functioned and performed 100%.
The texturing on the SS80 is perfect and looks really good too.

Decent product so far


Amazing frame in regards to grip and feel however as fun as it is to shoot i have noticed two problems.
1. The trigger would occasionally not reset when dry firing or when shooting, out of two hundred rounds the trigger did not reset twice. I'm hoping this will cycle itself out and am associating it with a new build break in period. after 200 rounds it seems to be resetting every time during dry fires.

2. The rear pin also walked out during my range test. obviously this is a problem ill see if it does it again and if so ill remedy with some blue loctite. I did use the pin that came with build kit.

Again over all, I enjoy the product and it functions I will be updating this review too five stars if these problems do not persist and its just new build bugs.



Fun to build, shoots great. I have put a few hundred rounds through it without any issues using all glock oem parts. The wait was worth and and couldn't ask for any better.

Great kit with a few small problems!


Finally received the kit after a real long wait. I must say that I am very pleased I waited. I got the package on a Wednesday and had the project completed in about an hour. Just follow the videos and it is real easy. All the drilling sanding etc. came out perfectly and it looks factory! I just ordered a bunch of extras with my 20% off email that I got for the long wait time! I might even get a second kit and build another all custom set up! I did not experience any problem with the front rail block as others have indicated. I can, however, see how a second pin may help stabilize the block from moving around after multiple use. Also, the screws provided in the jig are useless because they are too short and can’t be tightened. I suggest using your own screws for this to make sure the jig stays closed. Hope this helps

Worth the wait, will purchase again.


Built the ss80 wasn't difficult at all , I had access to a drill press. My slide release is a bear to actuate however and its pretty small, so upgrading to the enhanced, as well as take down .

Best build ever


I have built the polymer g17 g19 own a glock 20, by far this is the most fun on a build I have had, I stuck it out put on my ss80 core backplate and I'm just in love! Thanks Lenny and everyone at glockstore I'm very impressed!

A+++++great build get product.bit worked right away after trim


I am impressed. Grip feels awesome. Perfect rough feel to it. Plastic of frame seemed nice and hard with consistency thu out. Once trimed up. Worked flawlessly right from beginning. Long wait for preorder but totally worth it.... Thanks glockstore for great preorder and extra back plate

Excellent design, be careful, and enjoy your new toy


Overall this is a great little weapon. I took my time and did a careful and accurate job of machining and assembling it. Be careful it would be easy to slip and take off too much material if you rush. I also received screws too small to reach the nuts on the jig, had to make a trip to the hardware store for some longer 10-32 screws. Be advised, Everything, and i do mean everything on this gun fits very tight, taking the locking block out in order to assemble the lower without doing damage to it was next to impossible, maybe some lube would have helped. If you use a hand drill be sure you are straight and steady, i chose to use a drill press, and wouldn't think of using a hand drill unless it was my only option. Once together everything fits and works as well or better than a standard G43. And it's a fun project too!

SS80, it’s a win, a no brainer!


Well today I took my SS80 build out for the first time. Wow! What a shooter! I put 150 rounds through it and not one misfire, not one failure to feed, not one jam! It ran flawlessly. The complete upper is factory Glock, the trigger group is factory, and the 2 mags are factory. The only two upgrades I did were the extended mag release and extended slide lock. These are a must. The factory slide lock is so stiff you have to adjust your grip to release it. All in all, I will build another. Quality, quality, quality.

Note on TLR-6 installation ...


Continuing to tinker on my SS80 G43 back-up piece ... mounted a TLR-6 to have a light and laser, instead of the CTC refurb laser-only with pressure switch under middle finger ... I prefer to not have the light or laser come on as soon as I get my grip, in case a "baddy" would see it and it gives away my position before I can get him in my sights ... ANYWAY .... just wanted to let others who have this combo of frame and light/laser in mind for themselves or as a gift to an owner of this frame, that in order to make it fit securely, without wobble, I had to shim the trigger guard and under the recoil guide (serial number plate area) with some Moleskin and double-sided sticky foam tape, as the TLR-6 is only held on the gun by the front portion of the trigger guard. Evidently, these SS80's are a little different in that contour from the Glock factory 43s. Love this thing so far, and probably will even more when I get her out to a test-fire site to launch some copper-jacketed lead !
