have moved it a bit, and settled on 3'o'clock. Depending on pants, try to keep it clear of both front right and back right pockets so i can get in and out easily with a hand for wallet/whatever. It feels best there. Carry a mag at 9' if i'm in dress clothes,, gives symetry, or my cargo type pants, 5.11 have a mag pocket around 11oclock. I can keep my thumb in my right pocket with my arm over holster...keeping contact and feeling in control. I've only really tried drawing and firing from 3 o clock. Any closer to my crotch seems like i'm flagging something important....and further behind seems like unnecessary movement.
CC'ed with holster tucked in at 12 o clock...felt weird, especially sitting, and at 6 o clock...the 6 o clock gave me a bruise after a few hours around my spine heh. Since I OC most times, the CC times were rare, hence more use would probably be less bruising.
