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 would look better polished up and shining through the slide. I was rather disappointed when taking the finish off that there were quite a few tooling marks and dings in the area I was working on that were just "filled in" with the coating that Sig used. I managed to get everything smoothed down and shined up and I think it looks damn good for an in home job! I'll post some pics up sooner or later its just a pain trying to load anything off my phone! But anyone who has had similiar experiences with this type of thing I'd love to hear from you and know how everything turned out for you.
