There are two that I would grab that come to mind.
Both happen to have factory guarantees of accuracy that happen to be the same.
1.5"s at 50 yards.
The first is my Baer 1911.
The second is a Classic DX Model 29. 5" .44 Magnum.
I happen to have a 5" M29 Classic non "DX" version, with an RDO on it, and it is quite fun in terms of driving tacks.
