skippjones: There are any number of western holster makers to choose from. Your choice depends on how much you want to spend. In your back yard, Last Best West would be a good place to start. Then, there's site sponsor: Marstar. Some reasonably priced options to choose from on that site.
Another good Canadian leather maker: Working Cowboy Gun Leather. Based in Chatham, Ontario.
Likely the easiest way to get an idea what's out there, is to simply google: Western gun leather makers. That should turn up quite a few sources, including: Mernickle, El Paso Saddlery, Kirkpatrick, Doc Noper, Tombstone, etc. Plus, many more.
Depending on your intended use of the leather, ie: cowboy action, range use, plinking, etc...there are quite a few folks on here that can offer very solid advice on what to look for. If you can be a bit more specific as regards your needs, it will be helpful in narrowing down your choices.
If you're reasonably handy, you could even make your own belts, holsters, etc. Lots of how-to videos on you tube.
