Tom Coal with cadiz gun works. he is in southern Ohio but you can find him at just about any gun show in Ohio. He also works with Chris Reed with ASA (American specialty ammo). The company i work for. Here is his website.
If you contact him let him know that Eric with ASA sent you to him. Might give me a deal on the 9mm conversion barrel I'm trying to get off of him.
