Aristotle, I like the finish on your slide what is it and who did it.
Yup, it's raw dog. I had a bladetech holster that scratched up the finish pretty good on the gun, and it was brand spanking new. I experimented with grip tape on the slide, and it scratched the inside of the kydex, which scratched up the finish of the slide. After a few days of dry fire/Dry drawing practice I noticed the damaged I did to the slide. So i decided to take it off completely. It is only polished on the side of the slide, and that's it. I left the top and rear black/tennifer. And I polished it myself.
It was experiment, and my back up plan was to have it treated/coated if I didn't like it. I ended up really liking the results. No issues with it so far. then again, I handle the gun when I'm at home all the time so I'm able to really watch any issues with it like that. And it's strictly my game gun. I get asked all the time about it now.
This may sound stupid but did you use, a dremel or a bench grinder with a polishing wheel. I think I may try it.
