What about an XD?
I have short sausage fingers, and I look for "small" grips myself. One thing I have noticed it that the grip circumference has a lot to do with how comfortable it feels to me. So it is really a combination of the grip width and the grip depth (side to side as well as front to back measurements.)
The double-stacks that feel the best to me so far are the CZ's, the Ruger SR's and also the SA XD. I do not know how the grip width of the XD compares to the SR, but I think they are shorter front-to-back, which helps it to feel slim.
