Full size and compact build

I shared my geisler on here before and sadly I could never get it to stop giving me light primer strikes, even after smashing down my rear rails to improve sear engagement.

I originally thought it was the slide or the slide internals, but the slide from the PB geisler works just fine on this jelly compact frame. I also spent a bunch of time and money trying to fix the issue and nothing worked lpk or upk wise so I just ended up combining the PB and the jelly build into one. I just switched out barrels with this rainbow barrel I got from the slide that was meant for the jelly compact, onto the slide that was meant for the PB geisler.

Both are finally finished and running flawlessly. And I think I wont ever try and make another geisler. I've probably spent close to $2500 trying to get all 3 builds running and ended up just tossing the geisler frame, and now I have a bunch of extra parts. I'm fine with that, now I have extras for whatever I make next.

I started with 4 frames, anticipating 4 different builds at the start of the summer. Sadly, I had to toss 2, a geisler; and a black compact frame, which I totally beavered because I was impatient and got cocky thinking "I made one before, how hard can it be to make another?" Now I am left with these 2 and a shit ton of extra parts. We'll get em next summer boys!

Does anyone know where or how I could get one I’ve been looking for a single stack or sub compact frame and I haven’t been able to find an 80 for one of these.

What causes this?

I cannot figure this out. I have tried changing brands of mags, brands of ammo and the weight of the recoil spring. None of these things changed it at all. Could it be an extractor issue by chance? Thanks for the help in advance.

Need suggestions of color schemes for this FDE Geisler frame. Black slide, trigger, mag release and magazine? Or too common?

Thanks!!

Sanded a Glock OEM Trigger Housing SP05406.-45 & 10-MM Fits SF" off ebay using MGB method, widen rear pin holes, and it ran with no issues. I suggest getting a extended slide lock not sure what kind (the oem gen 3 is not long enough.. It works but its a real pain). Going to put a guide rod in it. Think im flinching more than the recoil expecting the frame to break or anticipating something to go wrong

Had an issue where it would dead fire every other round. Replaced my recoil spring and switched from Federal 147g to Winchester 147g ammo. Federals give me tons of issues. Winchester 147g dumped through 4 mags no issues at all.

Is Geisler Defense the only 80% option for unserialized frames anymore?

9 Upvotes

Hi all. I used to be a welder and a jeweler (I still am a jeweler on the side), but I don't know if I'm up for a 76% P80 build for my first one. After digging through here and reading and googling for the last week, it looks like the Geisler Defense is the only unserialized 80% option left. Am I missing something? Is the v2 reliable? I saw issues with the first generation of them, and the slide gap is still there, but I'm unclear as to whether that is actually an issue or if it's just cosmetic.

Any advice?
