During summer when wearing mostly tee shirts, since I'm somewhat a portly person, I carry my Glock 19 in a G-Code "Comfort Carry" IWB at 7 o'clock (I'm left handed), and in the winter when I can use heavier shirts, I carry my full size Springfield 1911-A1 in a Blade-Tech IWB also at 7 o'clock. Both guns are very comfortable to carry and conceal well. I switch to OWB paddle holsters on match days so I can set it to the IDPA required position as my normal IWB carry sets it a bit too far back for the range requirements.
