I thought I would post this information here. In case you are worried about getting your Scandium 1911 worked on to add custom features that would require cutting or milling the frame, here is the quote from the email I got from an engineer at S&W:
"The Scandium is in the metal of the frame, not the finish."
This would eliminate the concern or need to re-anodize the frame for hardness. The Scandium is part of the aluminum forging, not a coating. This means that you can get the gun refinished in whatever finish that you like after the work is done without any concern over anodizing like some of the other aluminum framed pistols. FYI.
