I cant pull back the slide all the way. The thing is completely built… trigger pin, charging handle, etc. However, I cant pull the slide all the way back… The slide fits onto both front/rear rails. I just cant pull the slide beyond that. I can take the slide down using the takedown button. So… what am I missing here ?
Ive built numerous glock frames… so not a newbie…
Thoughts ?
I just built up my Franken9 frame and have a very similar problem. The root cause is the recoil spring stop in front of the slide lock. The back of the recoil spring guide rod is supposed to butt up against this:
In the Franken9, this is V-notched for some reason.
That lets the guide rod pass through the stop and butt up against the slide lock. Depending on your parts, the barrel may then bind on the guide rod when it’s trying to drop into the locking block. Even if it doesn’t, this isn’t the way you want to run the gun since the slide lock isn’t designed to do double duty as a guide rod stop.
It’s possible to get the current frame working correctly by cutting an appropriately sized steel washer in half and epoxying one half to the front of the guide rod stop.
“appropriately sized steel washer in half and epoxying one half to the front of the guide rod stop.”
ill just wait for the corrected design and/or an official USK release. thanks for your support here … glad i wasnt the only one who experienced the same.
the one piece I trusted was using good cad, sigh
yeah i’ll hit it hard and it will be fixed ASAP
Mine worked the first time until I disassembled it and reassembled it. I figured out the same thing you did, but I messed with it a bunch (including not installing the recoil spring assembly just in case it was the barrel lug and locking block–now obviously not it)
I can see how the beta testers could have missed it because it got stuck 4 out of 5 times at first (my first successful try was a fluke), then I was able to figure out a technique to get it seated correctly every time. But even if seated correctly, if you just nudge the guide rod a teensy bit you’d hear it slip and it would get stuck, lol
It’s good it’s fixed now but the struggle to figure out what was going on was actually pretty useful to me, I’m now way more familiar with the internal workings than I was at the start (not the first time this kind of thing happened in 3D2A, of course)
