Sorry, but that's just me. You have what looks like a nice specimen and not what I would consider a candidate for refinish or modification. Maybe start slowly with a different grip, then swap stainless controls for blued, or swap blued hammer/trigger for stainless? It can be interesting to try different combinations to find something that has a sharp look that appeals to you.

I'll bet a blued slide from a 5904 could be installed and you'd have a pretty sweet 2-tone pistol.

You did a great job with disassembly! My luck, I would end up missing a few springs or pins when all was said and done. You say you have zip experience but I admire your can-do attitude. Love to hear what ideas other members have.
