I want to build a complete DIY 9mm. I currently have 42crmo 16OD/8.3ID 300mm steel tube and as far as I know it is perfect for fgc-9. Any other recommendations, maybe a handgun?

Fully DIY 9mm handguns aren’t viable yet. Simple blowback designs like the FGC9 don’t scale down because you need about 500g of bolt weight. Until someone comes up with a viable locking mechanism, PDW size is about as compact as you can get.
More modern DIY alternatives to the FGC9 include Rogue/Rebel and Urutau. The Rogue/Rebel designs are very full-featured, but making the bolt is more work than other designs. Urutau is a pretty easy build and a really enjoyable gun to shoot.
We’ll hopefully be able to add the Decker 9 to that list soon.
Thanks for details. I just inspected the documents of Rogue and Rebel. It feels like they require too much work to do without a drill press or a CNC but I have no rush, I can take my time to build something.
If you’re not in a hurry you might want to consider the Decker 9. It’s currently in beta but it will be very similar to the 380 version that’s available now. It’s a very easy (and inexpensive) build and has some cool options like side feed or top feed, different fire control groups, etc.
