The best 9mm 1911 ever made is a Browning Hi-Power, full stop.
The next best would be a commander length single stack gun, a Dan Wesson or a Wilson.
I would not buy a 9mm 1911 in full size, nor could I be convinced to carry one. I'd rather spend the money on .38 super ammo than go with a 5" 9mm 1911 of any flavor.
Yes they can be made to run and run well, but the best of those running are commander sized, I take that as a clue.
My only 9mm 1911 (technically 2011) is an STI in Commander length. Next 1911 will be a CCO in .38 Super I think, with maybe a 9mm as my trainer.
