I carry two ways: IWB at appendix (most of the time) and OWB at 3:30 to 4:00 o'clock (sometimes). Both of my holsters are from Srigs, who used to post here. He still might, but I haven't noticed him in a while. His website is:

Comfort. Only you can tell what is and is not comfortable. Try several models when you get a chance and see which feels ok.
Quality. Soft leather or suede, IMHO, suck. Don't expect to get a functional rig on the cheap. There are some things in life that just can't be had without spending money. Interior house paint, tools and holsters are among those things.
Gun fit. "Pretty close" is not good enough. A gun should fit PERFECT in a holster. The two holsters I got from Eric (Erik?) were made specifically for the gun I carry. I have several rigs that sit in a box under another box somewhere in the basement that said on the packaging that they would work for a list of guns. Yeah, not so much.
Stability. Your gun/holster should be in the same place all the time. For example, I've gained a little weight in the last few months so I'm not carrying at appendix right now (the holster pushes out and the angle changes cuz my gut is a little bigger than it will be in June).
Belt. The belt you need to hold a holstered gun in place IS NOT at Target or K-mart. You're gonna want something with more strength and rigidity than you might be used to wearing. Get used to it.
