Kahr PM9 in pocket holster, or IWB. This is the most comfortable for me.
I needed to pick up something extra though, because it was in for service. I got a Smith M&P9 sub-compact. Its a little bigger in length, and certainly wider. However, its got about double the capacity. I can carry it in my pocket, but its a little big/heavy for that. It'll be great in a IWB.
I seriously considered the Keltec PF9 and P32, but I just can't trust the Keltec brand. I think they've made huge improvements, and the price was right, but I opted for the smith.
