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?

    Thanks. I assume the steel tube (16mm OD/8.3mm ID) i have is oversized for .22 builds, right? Maybe I can get a steel tube locally that is okay to use with .22 ammunition but I am not sure about that, other than 304 and 316 steels are hard to get locally.
