Read all of this thread. Good grief! I have a 9mm Shield, a 40c, and a 45c in my MP collection. I carry them all depending on what I am wearing. I can carry my 45c for 12 hours no problem because I have a great gun belt and a comptac minotaur for it's holster. If you have the right holster and a good gun belt, you can make most handguns comfortable IWB. I carry my 226 extreme in a supertuck and I can definitely tell its there, but I don't carry it when I'm wearing dress pants or sweatpants..... If you want something to throw in a pocket, buy yourself a pocket gun! Which a shield is not. IMHO.
