A few things can be done...... A- Polish the entire slide out to a mirror finish B- Use a sharpie to cover scratch C-Send back to Glock in Smyrna and have it re-coated D-Send it to one of several companies that do laser etching and have a custom job done. E-Have it Durocaoted another color F-{probably the single best solution}......enjoy it's new point of character, not worry about it and keep on shootin'!
