I posted here a couple of weeks ago about looking for an engraver. Well I found one close to my house. Which turned out to be an awesome experience. They usually do factory engraving for Colt. They took the time to do my little old form one engraving. They also make bullet pens. I am considering commissioning them to due a 1911 any body have any recommendations.
