Congrats on the 938. I've had mine a while, and it's been 100% reliable.
Consider Zorn Holsters:
Zorn Holsters
Thin kydex, excellent construction. They make IWB and OWB. I have several of their IWB, they just plain work.
When I got my 938, I wanted their holster for it. I called, and they did not make one. The owner got a 938 to mold a holster for me the same day, and shipped I believe the whole process took a week, from order to door.
Quality construction for a very reasonable price. i have 3 of them, all IWB for a G36, XDs and the 938.
