Barring something custom as krshunter mentioned, I'd look towards the Bianchi Cyclone holster. It can be used as a crossdraw or strong side holster. It is great for hunting and hiking as it offers protection up beyond the trigger group which really helps keep crap out of the action like dirt, weeds, etc. They run about $50 plus or minus. I use one for my Mountain Guns when I carry a sidearm into the field.
Here's a partial look at it....
