polishing

Was windering if anyone knows how to shine my 320 slide , don’t want mirror finish or strip to down just want to add a slight sheen to part of the matte black slide to give it a two tone look of shiny nitride and matte, still want to keep the same finish. Any ideas will help , thanks

I recently polished the chamber on my P226 Tacops where it shows through the slide when its at full battery. I did this because the finish on the area was wearing off and it was just generally starting to irritate me. I know its a natural occurence that its going to wear off I just figured it...
