I have an RIA 1911 tactical handgun. It's my first and only .45 gun. I like the fact that it was inexpensive, and like the way it feels and shoots. The main thing I don't like about it is the appearance of the barrel at the ejection port. It looks really rough. I was thinking an engine turned finish would look really nice. Being as cheap as I am, I would like to do it myself. I have numerous Dremel and air-powered tools. What I don't have is the knowledge of how to achieve the finish, and what specifically I would need. Anyone out there can help?
