This is a Wilson Combat heirloom “Dream Gun”.
The renowned Supergrade pistolsmiths started with a Wilson Combat Classic Supergrade in .45 ACP, added some tasteful,  hand-cut engraving to the masterfully blued slide and then had Doug Turnbull color-case harden the frame like a fine turn of the century bespoke gun.
Added a unique set of rare Mastodon tooth grips (not tusk, tooth!) and this is the end result.  A real Show stopper at home or on the range that is destined to be the centerpiece of any 1911 collection.
If you shoot 10 rounds or 10, 000 rounds in year It is built, like all Super Grades, to be the best guns.
