Dave also makes them from leather I believe.
Here is a copy and past from his home page
(The number one reason, all the others that I'm aware of are too noisy. I use a liner that substantially quiets nylon and almost makes leather dead silent. The typical nylon holsters on the market, use a 3 layer system with closed cell foam sandwiched for padding. This produces a "drum" effect. And traditional 8-10oz. leather squeeks when weight shifts.)
Give him a call,
he is a great Guy,
I have talked to him a couple of times about my needs.
