I've seen several pictures of these floating around. I think I should probably have one. I saw the first one on JMC Custom Holsters' page, the second on the Four Guys Guns Facebook page. I'm not sure if either one is going to be carrying them in their store. If not, I reckon you could prob'ly make one yourself if you can't find one to buy.
If anyone knows the source of the Gyrene picture, let us know so we can credit them.
