When I first started, I made my rig out of old holsters from the holster graveyard box. I made a nice x-draw out of an old hunter holster, took off the thumb strap, a piece of raw hide for hammer tie down, and a couple of chicago screws from a sling to give it the right angle and to tighten it up. I used a regular belt at first, and then boght a Bianchi cartridge belt.
Look in the Dillon catalog. San Pedro holsters are there and fairly reasonable. Still not cheap. That is what I use now, and am welll pleased. Just add on a little at a time.
