What barrel length are you looking for? That makes a big difference in my holster preferences for a revolver. Since you mentioned IWB, I'm going to assume you're looking at a shorter barrel.

The Milt Sparks PMK is my favorite for a shorter barrel concealed carry (or not concealed) N-frame with 3" or less barrel:
