What's your price range? If you aren't adverse to spending in the $200-300 range you can get an incredible quality holster from Mike Barranti, 7x Leather, or Grizzly Leather. I have a 7x that I bought 5 years ago for my 7.5 inch Super Redhawk and it's well worth the price. If you are toting it through the woods for any distance a well made rig will make the weight and heft more than comfortable. I've done 7-8 miles in a day with my rig and not had any issues.
I believe Barranti also has some more economical holsters that are less than $150 for a tanker style rig.
