I've pocked carried an EMP, a Glock 26, and recently got a Colt New Agent for pocket carry. Yeah, they are on the heavy side for pocket carry, but you can certainly do it if you have the right pockets.
I have a bunch of pairs of shorts by Columbia (I forget the model name) that has REALLY big, deep front pockets. There's a cargo pocket sewn on top of those, which does a great job of breaking up any outline of the pistol in the front pocket (in a pocket holster, of course).
I found the Glock 26 to be a bit thick for this - it would bounce around more. The EMP worked pretty well, but I prefer .45 if possible. The New Agent has been great so far, the lack of front sights makes it very non-snagging when drawing from a pocket.
Note - I by far prefer IWB carry, but in the summer when I'm in shorts and a thin t-shirt I find it difficult on my frame to hide IWB - pocket just works out better for me.
