So I am working with a custom gun smith on a full house custom 1911. I have the build pretty well nailed down but I am debating the finish. I love a blued gun. I was going to to polished flats matter rounds. I don't mind holster wear but protecting the gun from rust is a consideration. The other option is Ion Bond which will be much more rust and wear resistant. It can be done in a blue like finish but not quiet the same. The other downside is the cost. It is almost double what a good bluing job costs. So what do you guys think? Blue or Ion Bond?
