For multi-material (kydex with leather) , I like Aliengear.
How you plan to carry may move you to look at other manufacturers. I've read good things about Vedder holsters, but i haven't tried them. Their most popular line seems to be AIWB.
I ended up going back Ares Tactical. Matt is easy to communicate with, responsive and his product meets or exceeds expectation. He is not cookie cutter. He makes what you want.
