You are probably going to have a hard time finding a pattern exactly what you need. If you have the Stohlman book it tells you exactly what to do to create your own. Basically you fold a piece of heavy paper in the middle, put the gun on it on the barrel, sights down. then roll it to the left, for a right hand gun, and trace around the gun. Add about an inch to the tracing rounding out the curves, cut that out and fold it over and trace around it now you have the pouch. For the belt loop you need to refer to the book, I don't have it right in front of me but it will walk you through the process.
