Best shooting, Springfield 1911 RO in 9mm (Point Blank in Carmel had one to rent a while back); but I think Colt Commader (now back in production) because all 1911's should be Colt's.
I have shot both Colt Combat Commander (steel, not currently in production) & Colt Commander (alloy) in 9mm and they are great.
