There are many methods of carry, and some research can get you all that. I just wanted to make the point that the most important thing is that however you choose to carry, it is in a place that is easily and quickly acccessable yet concealed. This means that you want as few steps as possible to access your weapon, draw, and fire. So, a behind the hip, side hip, or front hip holstered where you can access it without having to fiddle around with clothing, zippers, etc., would be better then, say, an ankle holster, a zipper pocket or hipsack. Not saying that ankle holsters or hipsacks are bad, because they have their place. I am just using these examples to illustrate a point. Also, keep in mind that a lot of carry methods are very specific to certian situations or attire, or better for carrying a secondary firearm.
Also, you might want to think about how you will carry your extra magazine. God forbit you'll ever need one, but if you do that won't be the time to find out that you chose a poor place for access and an efficient mag change.
I wish you well on your research...
