When I first got my pup I went to my son's in Dayton Ohio with a DeSantis Nemesis I purchased at the dealer. Not pretty, functional but not quite the back pocket holster I really wanted (and I had a Meco on order).
At a gun store there I saw some Stoner Holsters on display and they looked pretty nice, but nothing for the R9s there. I visited their website:
http://www.stonerholsters.com/index.php?main_page=product_info&products_id=112and saw not only that they did make for the Rohrbaugh but were less than 20 miles from where I was. I called them, they had one in stock, so I drove over and bought it.
What you may not "get" from looking at the website pictures is that it fits the pup very well - the molding is just right - draw is easy and the gun comes out and the holster stays in. The back flap is rather soft so it conforms to the pocket well and "breaks-in" easily. The gun fits all the way in with a very slight muzzle protrusion and the back flap is no bigger than it needs to be which makes it fit the back pocket of my jeans and the gun totally disappears.
For the price (and availability - they are only 2 weeks even on a special order) it's hard to beat it.
They sort of won me over with their sign on the front of their store:
"Ohio CHL license holders and their weapons are welcome inside. Criminals must leave their weapons outside."
