Well, I was going to suggest Comp-Tac. This is what I went with for my P30. The price was very reasonable and contrary to their claim of it taking a while, it was at my doorstep in very short order.
Call 'em up and talk to Erna or any rep there. My wife used the holster as well as mag pouches at a recent course we took and she's their biggest fan.
Since K-Man has chimed in, though, I'd have to reccomend their holsters as well. At the time of my request for a P30 holster to be made, they werent' geared up for them in time for our course. However, I have 3 holsters and two belts from KD Holsters. I'm extremely happy with the quality of leather, stitching, fitment, and style. On top of that, I received excellent service and the prices were VERY reasonable.
