I'm currently stationed in Alaska, not leaving anytime soon, and I'm building a 1911. Most of the parts, Damascus slide and barrel have been secured. I still need the frame, and it'll be Caspian. They have the carbon, stainless and titanium, but the last one does nothing for me really. The finish is going to be severn custom hard hat finish, so it'll be the same visually either way. I'm assuming you guys know to somed degree the different traits, but the environment up here goes from balls cold to warm and moist and terrible for unmaintained guns. Why one over the other, or will the finish make where it doesn't even matter?
