Well, the OP might get at some kind of answer by looking at some previous INGO polls.
Most people on INGO (the largest group) seem to carry IWB on the strong side [1].
Also, most people on INGO seem to carry a semi-auto rather than a revolver. I'll say at least 75%ish. (I won't bother to cite the polls on this.)
Furthermore, the largest group of people also report carrying an auto of at least medium (to full) size with a 4" barrel. [2]
Put that all together and I think you'll find that carrying at least a medium-size semiauto (ex. Glock 19 or similar) in an IWB holster is a very popular option.
Eyeballing the responses to this thread so far seems to confirm this once again.

Was wondering what everyone is carrying now days when something more than a pocket carry is possible? (i.e. IWB holster under a square cut polo jersey, jacket, in a vest etc.)
1: A "large" pocket pistol (i.e. Kahr or S&W J Frame)
2: A subcompact full size pistol, such as an officer's model 1911 or the Sphinx SDP Subcompact is looking interesting.
3: A compact full size pistol, such as a Glock 19, USP Compact, Commander etc.
4: A full size pistol such as 1911, USP, M9, FNX, CZ75 etc.
Thanks
