I am back to saying to run a search, but part of this is because there are a lot of good leather makers out there and this site has several areas that get threads on it. The pistol section should have some stuff about carry belts and I know general discussion has had threads on them.
Some of the small time guys are on amazon, read the reviews and see what you think. Due to a time crunch I ordered a thick heavy duty 2 inch wide belt with one of the 2 hole setups for the belt buckle, most belts use 1 hole for the belt buckle pin and this one has 2. When he said 2 inches, it was 2 inches. Not 1 and 7/8s like most folks. Heavy duty leather for one nice thick belt instead of some cheap leather stitched to more cheap leather to make a belt. Now some places add a stiffener in between layers and if done right I could be happy with this.
But wanted one big heavy duty belt for work, got it.
When not in a time crunch I use a local guy. It is more of a hobby for him but he does a heck of a good job. He made his first holster and speed loader holder when I asked him to make them along with a belt and it took a bit for him to make something he was happy with. I love em. He asked lots of questions and since it is for playing around outside on the 4 wheeler and what not he went with oil based dye instead of water based since it should hold up better to the expected use.
Now some of the stuff above is very nice stuff and gets mentioned in about every thread.
I like local if I have the time to wait.
I tried out the fella on amazon when time was not there to wait and his reviews said he backed up what he advertised and I agree.
