Sebago Son said:The finest IWB holster I know of is the "Summer Special" originally designed and produced by Bruce Nelson and now made by Milt Sparks.
I can recommend the Bianchi Pistol Pocket. I've used one of these for several years.... A little more bulky that the "Summer Special", but it has a pivot and the thumb break which I like.

As an alternative, I also like the S.O.B. (Small of the Back) made by Galco. It's not IWB, but it's still very concealable.
