I got my Desantis thumb break holster in recently:
And, this is the WRB holster I have been using for in the pocket carry. I actually got a new WRB holster for my Shield. But, the Kahr PM9 one I had works better. I popped out 2 stitches for the trigger guard, and the Shield fits great in the Kahr version of the holster.
If you get the Shield version, the holster tends to come out with the gun.
