Another vote to check out Galco belts.
With that said, my favorite is Beltman's double-layer gun belts. I've been using them for several years. I've got a 1.5" bullhide, 1.25" bullhide, and currently using a 1.25" horsehide belt.
Since you mentioned hiking, you might want to check out one of the many nylon belts on the market. I believe the originator was the Wilderness Tactical Instructor belt, or the non-metal Frequent Flyer belt. They work quite well, especially if you get the 5-stitch or reinforced models for extra support. Being nylon, they'll be less affected by sweat than leather belts. However, comparing my Frequent Flyer belts to my Beltman leather belts, I find I get better support with the leather belts.
Another suggestion would be to try and find a belt that will fit snugly in your belt loop. It'll help keep the gun stable in place, which will help make it more comfortable for you.
