Wish I could help but I make my own leather holsters instead of buying them. Good leather holsters are usually expensive, you could try looking on ebay though.
You can get Serpas in brown which looks similar to leather. You can also inlay poly holsters like serpas with proper preparation of the poly first. PVC cleaner(yellow can) and contact cement on both leather and poly will dress up a poly holster.
Maybe Grapeshot will post a pic of his inlay holster. He has mentioned it, but I don't think he has posted a pic of it.
