If you're looking for something like the Kangaroo or a bellyband, you might also consider a holster shirt. There are several manufacturers that make them, and I have a 5.11 holster shirt. I've worn it with a dress shirt and found it to offer reasonable concealment with my Hi-Power - same size as a full-sized 1911 with a thicker grip.
I have a brief review with pictures here:
