You can make up your own as well. Tandy leather has all the tools for it at under $50 for leather and tools you'll need and the expert advice to go along with it. The first one you make will do the job...the 2nd will be good enough to show off to friends, the 3rd is Christmas gift quality....and believe me, if you like and carry your guns, you won't stop with just three.
My sons and I have made literally dozens for ourselves, friends and family, adjusting designs to fit our whims, but usually come back to the tried and true old Tom Threepersons type. El Paso Saddlery has them and not cheap either, but made with first rate craftsmanship and materials. You can't go wrong with one from them.
Here's a home made one of ours...you can do as well with a little practice. Belt, sheath, holster and knife were all made here on the farm. Rod
