I carry my Shield at 3 o'clock and it works fine, very comfortable with no printing. I tried it at 4 and everything was fine standing or walking but sitting was not comfortable at all. I'm 6'3" and about 190lbs so the fact I have very little padding back there could be the problem. A buddy of mine carries a 1911 at 4 with no problems but he is in the 230lbs range.
