Conservative Creek Holsters
I know the owner personally. You won't find a better person to deal with. If he doesn't already have a holster designed that you like, he'll make one. I have a Thunder Pro 9 as well that he could use to make a template if need be. He's located in the Mishawaka area.

You won't be able to see it before you buy, but they have an awesome return policy. I own one myself and love it!
I bought one last year at the 1900 from a company out of Ohio. I will try to find the name this evening. It is all leather and wonderful
