Its the builder not the gun
This is a Geisler Defense frame that i swapped p80 rear guid rails into and Stiffler slide with all Glock oem internals lok and upk with over 5k rounds all 124g Federal FmJ and a few boxes of Fedral hollow points I saw a video about how unsafe p80s and 3d printed guns are and figured id show a different opinion

2 years in the making, developed and designed by us and Standard Co USA. The Lotus a Superior Trigger shoe. Available tomorrow at www.superiortriggers.com

This is a zaffiri precision barrel on my first build I did a while ago.

Occasionally it jams like the picture where the nose of the round sticks against the feed ramp of the barrel. It’s obviously worse with hollow points compared to fmj.

I did some research and tried a few things: 1st: I polished the gold off of the feed ramp and made it smooth.

2nd: The frame/slide gap seemed a little too wide so I resolved that by filing some material on the rail body.

3rd: Ensured I only used a OEM mag (with extension).

The problem still happens. The feed ramp is really steep. Is that how all g43 barrels are?

I’m willing to try any ideas at this point. Everything on the build fit together nicely. Do I need to just shoot the heck out of it maybe?

My slide keeps getting stuck when loading a bullet in the chamber and I have to push it forward also my guide rod sticks out

I purchased a G80 build kit that features an 80% metal SS receiver that you finish by grinding some tabs off using dremel grinding bits that they supply and drilling some holes. They supply a jig.

Grinding the tabs off and drilling the holes was actually quite easy, I was impressed.

But what is stopping me at this point is that after "finishing" the receiver my OEM Gen 3 Glock lower parts kit do not fit. Not even close. The biggest problem is the trigger housing. I used a digital caliper to measure the area of the receiver where the housing is supposed to fit and it is way too tight. And even if I make that area bigger, there is no clearance for the trigger bar.

Has anyone else experienced this?

I hesitate to contact G80 support because the last time I did that to, inquire about my order, they got a little snappish at me.

I'd like to hear if anyone else has experienced a similar issue. Or perhaps point out an error I might have made.

Thanks

So this is my current build I just wanted to do a 76 for shits and giggles and bo was there more shits than giggles lol . During my work I punched a small hole into the mag well . When I try a mag it doesn’t snag but I don’t have any parts installed and maybe the lack of tension is why. Do I have to start again or what , would hate to be out the frame but highkey knew what I signed up for 😅 I also know I have a ton of sanding and polishing to do but all advice would be appreciated.

So here we are… running “.45 GAP” and solving a problem that “never” existed until now!

Wanted .45 ballistics, and since PF45 frames are basically nonexistent around here well here we are!
the gap between the slide and frame is VERY noticeable. The slide was also extremely tight. I had to oil it and rack it about 50 times before it started moving freely enough to return to battery without hanging up.
This is probably going to be its first real stress test on the Geisler v2 running 230-grain JHPs. Curious to see how this setup holds up.

Hey Polymer80 Reddit- full disclosure i'm not much of a firearms guy (I support the right to own guns just not a fascination / hobby for me). I am here out of curiosity, not judgement.
The mainstream media (and government) seemed to share a pretty strong consensus that Polymer80 was a textbook example of exploiting a legal gray area under the false premise of being for "hobbyists" who want to "build their own" firearms when in reality everyone knew clear as day that the driving force behind Polymer80's success were criminals / unscrupulous individuals who had criminal records, ill intent, etc.
Again- not a super knowledgeable guy when it comes to firearms, so I'll be honest, based off the information I've read, the narrative seems like it checks out. But I also haven't ever gotten the chance to hear the perspective of Polymer80 customers like you guys who I'm assuming aren't all just a bunch of criminals. So my question to y'all is this- what was the appeal behind purchasing these over standard firearms? From what I understand a lot of the kits could be assembled in under an hour, so was it really a hobby thing? Was it an exercise of your god given rights as an American? Please share!!

So I just finished my G80 build, and I got all of my lower parts from Marine gun builder OEM when I rack the slide, the trigger does not reset unless I hold the trigger when I rack the slide if you guys have any suggestions, please let me know as soon as I fix this I will go out and test this for you guys

NoQuarterInnovations has complete serialized p80s is most of the colors for $50 a frame and $20 for the ORIGINAL rails. you’re welcome

There’s material from left to right that’s cylindrical. Does this need to be cleared or will it kind of disappear when drilling for the pins? Thanks guys. I’ve built a few p80s on the past but this is my first 76 and it’s been probably 6 years.

Went a little too quick with a chisel and went straight through the mag well. Is this still salvageable? I was thinking about getting some jb weld and a beater magazine to keep it flat, and try and glue it back together. What do yall think? This is my first build, not my proudest moment, still have some hope considering the malleable nature of the polymer.

I've ordered a new TriggerTech Legacy Special ACE

Has anyone fit these? I have a serialized OEM frame.

Slide is p80 pfc9 4in barrel with suppressor height sights

Frame is sct19 with the braun tactical light (streamlight tlr1 hl clone) which to my understanding is dimensionally identical... can y'all help me find a holster for ? Will a standard glock paired with the streamlight holster work?

This is my third frame build (don't have pics of the first one though). That very first one was a total loss because hand-drilling the pin holes went crooked; if you don't have proper machinery like a bench drill press, you're bound to run into alignment problems. My second one—which was an FDE frame—kept having constant feeding issues.

​Between purchasing multiple frames and dealing with a stolen package, I essentially spent what a 3D printer costs. Honestly, it makes much more sense to just get a printer, download the files, and print your own frames. Plus, you get access to a huge variety of other builds, like a G43.

​On this grey frame, I got a bit rough with the Dremel around the front pin area as you can see in the photos, but switching to the WEN drill press fixed everything and it cycles with zero jams now.

First complete build, lmk what yall think(suppressor height sights waiting for sight to come in)

I looked up how to check all 3 safety mechanisms and this one passes with flying colors. Has all oem parts, rook rear rails, had to get it serialized because my state is changing laws. Has excellent sear engagement too. I think im going to try finding a holster.

I’ve been having extraction failures with my g80, sometimes the casing is stuck in the barrel and I have to rack it a bunch to get it out or it just gets stuck in the slide if there’s anyone that can help please do:)

Shits lowkey getting aggravating asf not even gonna lie sb jus go ahead tell me wats im doing wrong ive got literally EVERYTHING EVERY-SINGLE BIT OF MATERIAL I CAN FIND AND SEE OUT OF THE FRAME WTF.

Also now that im sitting here thinking i did buy P80 gen 1 locking block which needs sanding to fit and stuff and etc.
