PCS:
Welcome to the Forum, and congratulations on your R9 Stealth.
If the holster wear inflicted by the former owner is an "itch you need to scratch," you might consider sending it off for recoating by Bearcoat, Wilson, or Robar.
The subject of holster wear to the finish of a pistol gives me an opportunity once again to recommend a product which I use on all of my guns -- Renaissance Wax. I started using it on the surface of my guns and holsters years ago when I learned that the NRA Museum uses it for its collection.

It has been six and one-half years now that I have been carrying my Farmingdale R9 on a daily basis. Applying Renaissance Wax to the pistol has always been the last step in its regular cleaning regimen. The result is no visible holster wear on the pistol, and the holster is as new (as shown in this photo taken this morning).
