I believe that Nighthawk uses their own version of Ceramic finish on their 1911s. And, I think CCR refinishing does a cerakote as well, but only in black. Apparently, he had some issues w/ the other colors and didn't like something about them.
The finish is supposedly, very durable and scratch proof.
Are U planning to do it yourself or send it off. I looked into it a few months ago when I was researching all the finishes. I ended up going w/ hard chrome. It is more of a known thing - I haven't had any real world experience w/ Cerakote, and I couldn't find enough comments from people who had it. U won't find a whole lot of people who have done the cerakote thing.
