Already own it, 1915 produced Colt 1911, with three notches filied in the frame, after shooting at least three Mexicans during the 1916 Mexican expedition against Pancho Villa.
I have a similar piece but from the Korean/Nam conflicts. No notches but it has history. Used successfully.
I have went back through this thread and there are some really sweet pieces in here. I must have all of the ones I desire as none of these has made my heart zing to the point I would sell something to own them. I love the ones I have and shoot the snot out of them at every opportunity.
