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 ?


In case anyone is still seeing this post / comment, the Franken-9 frame issue has been identified, fixed, and re-released. The file name is called “Unseenkiller and Corbat67 - Franken 9 - 1-2-2026 Fix.zip”, so when you download it, you need to ensure that’s what comes down. The post should also be renamed to “Unseenkiller and Corbat67 - Franken 9 (fixed)”
I’ve given the fix to Moderator Gage and he should be updating the BLC release file shortly as well.
Sorry again for any wasted filament or time, folks - this is my bad.
Never a waste when you learn something in the process.
