Ankle holsters aren't such a good idea. Inside-the-waistband in the appendix position (12-2 o'clock for rh, 10-12 o'clock for lh) offers best concealment and accesability. There are a number of very good holster makers, just depends on how much you want to spend. Don Hume, Comp-Tac, FIST-Inc come to mind. Kydex is best in my opinion, but you decide for yourself. Get training, best thing for you to do. Suarez International offers the best, and they offer classes on dvd's, so its easy to afford.
