I'm using two holsters. The Galco COP Series, CSL224B. If memory serves, it's made for Glocks.
For days when I don't have a belt, I've got a Galco black plastic holster that clips on. Unfortunately, there's no model number.. and I threw away the bags long ago. I'll be back at the gun shop soon, and will track it down.
I've got pics..
