Cimarron sells an Armscor 1911 (not A1) with a parkerized, blued, or nickle finish. The roll marks are even done in the style of the Colts.
As for a WWII style 1911A1.....
I have had one of these things for over a year and after a few thousand rounds it has not missed a beat. The only thing that sucks is the series 80 firing pin block but it isn't a problem.
