I don't believe Ron Graham is making / selling holsters at this time. I love his holsters and have three of them, but got them all from previous owners.
You might check with Kevin http://mecopocketholsters.com/
or Matt Del Fatti http://www.delfatti.com/ (4 to 6 month wait)
if you need some more choices shoot me a PM and I can give you some other makers addresses.
