84BB Mods and Maintenance

I bought an 84BB from PSA last summer thinking I could find anything beyond magazines for it, but unfortunately I can’t even find a properly sized recoil spring. It was supposed be my EDC but I’m thinking about saying screw it and learning metallurgy to make my own springs or getting rid of it altogether. Pretty disappointed as I have a 92FS with the LTT TJIAB and wanted to mod this one out for similar performance. Wat do???
