Or a holster with outboard loops, like the Milt Sparks VMII.
JM Kydex offers a kydex IWB holster for 3" K-frames, their IWB #3. I have that model for my PX4 Compact and it is a well-made, functional holster. However, it is only available with the clip/loops positioned directly over the gun instead of being offset. I'm not saying that makes it a bad design, but it may not conceal as well as one with an offset loop. However, I will add that I used to carry a 3" 65 in a Milt Sparks Summer Special II, with loops directly over the gun, and I was able to conceal it and carry it comfortably with the right clothing. Not sure how that would translate to kydex, though.
It would probably be a custom order, so it may take a couple of months.
