OP - I'd be interested in what the DeSantis model is you have. I am almost exclusively using DeSantis for all my pistols and they all ride high and body snug - from Mini-Slide and Mini-Holsters to 3-slot with and without thumb break. This is from small to large frame.
I quit IWB altogether in Jan 2015 when law changed for incidental exposure and went OWB with untucked shirt. Although I do not OC, when that went into effect, I totally quit worrying about exposure, hip bumps (otherwise known as printing) or what others may or may not suspect, granted I do not wear tank tops or spandex body hugging shirts.
