As a matter of fact, I have. About a year back, I had an ad posted in the ee (I forget what for, a blade perhaps?) And the owner contacted me about doing a trade for kydex work and he happened to own said company.
He did a custom one with a retention hood and RTI hanger for my P320 and let me tell you, the work was excellent. It is my sole holster for that gun and it fits and operates perfectly. I was very pleased. I can get pics in the morning if you'd like. I haven't done any hard core wiz bang use of it, but like I said, when I take that gun out the holster goes with.
