I know the threads a bit old, but just curious what you ended up deciding on. And as a side note, I used to carry an XD45 Compact in a Supertuck with no issues. I'm 6'3", about 200, and I could easily conceal it under a size large shirt, which is what I normally wear. I even carried it at work when I had to tuck my shirt in over it with no issues. I know you said you preferred OWB, but if you really want the pistol, IWB might be your only choice.
