Axeman, I have 2 suggestions for you, based on actual experience. For IWB I love the Galco Summer Comfort holster. It's small, narrow and easy to conceal. Pretty comfortable, too, although any holster is felt. For OWB, I like the Active Pro Compact Belt Slide. Here's a link:
Compact Belt Slide Gun Concealment Holsters
It is very narrow and fits between your belt and your pants. It holds my Kahr PM9 very tight to my body and is very small.
That's my 2 cents. Good luck
