I haven't found one but I did "make" one. I got a Safariland holster free when I bought my FNS9 long slide and modded it a little (part number 5199-266-411 on the holsters.com section of the website). It works perfect and feels awesome! It's definitely my range holster. Here's a video I made showing what was done.
I hope this helps until we all can see the holsters come out
