OWB - Milt Sparks PMK or 200AW. The PMK tucks the sixgun a little closer to the body, but the 200AW has a nice flap of leather that keeps the lining of the cover garment off the hammer spur. OWB is my preferred carry method. I do sometimes use an Eagle Industries nylon IWB, that has been discontinued, to carry up to a Ruger GP100. A Milt Sparks Summer Special should work quite well; though I do not have one made for a K-frame-sized sixgun, I do have one for an SAA that works nicely.
