How a given gun/holster set up works is a very individual issue - what works for some doesn't for others, depending on each individual's body physiology.
Here is what has worked for me, and maybe you can find something that will help.
(1) Use a good, stiff gun belt.
(2) Try several carry positions (3 o'clock, 4 o'clock, etc.) and cant settings. Forward cant seems to work for me.
(3) If you tuck your shirt over the IWB holster, as I do, "blouse" your shirt back over your belt in the gun area to create some space. BTW, shirts with patterns don't print nearly as badly as solid colors.
Bottom line, it's almost impossible to completely eliminate printing. Your awareness of carrying probably makes you much more sensitive to how you are presenting yourself, and the people around you most likely aren't noticing much, if anything, particularly considering all the contraptions people carry on their belts these days.
My setup includes an XD-40 4" service pistol in a CrossBreed SuperTuck Deluxe IWB holster on a Beltman gunbelt.
