The worst thing is I'm too fat to wear my IWB holsters anymore. 
I'm not sure if it is fat or body type, or both. I tried top quality IWB holsters from Kramer, Mitch Rosen, Milt Sparks to name a few.
I even bought pants one size larger to make room for the rig.
My waist size them was 33/34. I just could not make the IWB system work for me. I looked and felt like I had a cancerous tumor bulging. Or maybe I was just too self conscious.
Getting back to body types, even though my waist was not large per se, I have always carried a spare tire regardless of my weight and waist size. Maybe that counted for something.
