For a limited budget price the Auto Ordnance M1911A1 is a close reproduction of the WWII M1911A1. I had one of these and it was not too shabby at all.
Other then the higher visibility sights the new Colt Classic is basically the same gun but with post war rollmarks.
The Colt M1991A1 was billed as a continuation of the M1911A1.
Colt offered an actual reproduction but the only one I'd ever seen I would not have bought.
