If you want the Ferrari of the 1911 world, its a Nighthawk or Wilson Combat. I personally love the Nighthawks b/ of the shoot, form, function, finish, and reliability.
Currently have a Kimber Gold Cup Combat that I am happy with but I no longer run reloads through her b/ she can be picky if the loads are not full power. She is now a safe gun b/ I enjoy shooting her but have gone a diff route re defense gun.
IMHO, with a 1911, I have found the more you spend, the better gun you get.
I would have to throw the Ed Browns in there too.
