Buy more than one brand or style if you can afford to. Holsters are hard to recommend because everyone has their own personal preferance. I CCW with a Galco IWB holster worn at about 4 o'clock... but who's to say that you would be comfortable with that setup?
I started off with a Don Hume IWB carrying a Glock 23 at about 1 o'clock. Lol, I'll never go back to appendix carry. I guess my point is that you just have to try as many options and combonations as you can. If your serious about CCW, don't be afraid to spend a little bit of money on holsters. You can always sell the ones that don't work out for ya
