Hi Richie,
These folks have a few Roth Steyr holsters offered for sale :

Mike Krause also had a nice one with a should strap for sale a while back...not sure if it is still available or not. Think his asking price was around $ 500. It was nice and in great shape, but did have a previous owner's info. written in ink on the flap (if I recall correctly).
