I own a 70 Series Colt Combat Commander, and hate the sights. I thought it was a nickel or satin finish, but I have been told by a few gunsmiths that it was hard chrome. Apparently Colt did a limited run of these and I was told they are rare. I wanted to swap out the sights because they are hard chromed as well and wash out in the light. They told me I would de value the gun if i changed the sights, and ruin the finish. Part of me wants to do it and just cerekote the gun, the other part of me would hate to ruin this gun. Sorry about the title , EF spell check!
