Depends, if it had a metal clip and not any cant to speak of, I prefer to carry it at the 1 o'clock position, just to the right of my gig line. If it has a cant or belt loops etc, I probably wouldn't wear it but if I did it would probably be over the right kidney.
I wear an Uncle Mike's IWB just forward of my right pelvic bone. I find that it's comfortable here even with a seatbelt when I'm driving (I'm 6' tall and drive a Miata).
I tried wearing it on the left (cross draw) one time when I went to WalMart, and when I got home I discovered that the pressure from the seatbelt pushing the gun against my body had popped the clip! When that happens, you better make the first shot count because there won't be a second!
That's called the "Appendix Carry"... and it's the one I favor for in-car carry in Ohio, to comply with the idiotic requirement that our firearms be on our person in plain sight in our car.
