Thanks. Laser, mechanical ball or tungsten rod engraving? Cannot see details how well engraving turned out, but I will assume it is flawless. Some examples of engraving I have seen in the past have had somewhat unsharp definition and/or rounded corners on some of the letters, presumably from a mechanical ball engraving. What white paint did you fill engraving with? How does it hold up to occasional exposure to gun cleaners?
