My claustrophobia goes off the chart at the idea of anything tucked IWB. And totally uncomfortable when I tried anything above a pocket gun. Yes, Occasionally I will carry a small Micro 9, or Snubbie IWB But rare. Picture with people carrying them IWB and that huge area where the belt and pants waist having to accomadate that much room is not acceptable for me. I like my pants to fit perfectly and do not like to buy a larger waist size for a CCW. I like thin, light weight OWB Holsters and Shirt not tucked and usually with a coat.
