Yes, you can do it yourself. You start slow and go slow. I do all of my own polishing to my firearms. I use jeweler's rouge and a soft polishing " felt bob". Do a bit, and try it out.
I own an Alphabet Luger that had a very rough cut feed ramp(from the factory), and it was a jam-a-matic. I started with a wood dowel covered with different grits of wet/dry sandpaper for the rough stuff......then the polishing. It converted my Luger into a very happy gun!!
