It's getting so much praise because it's single stack and only 1" wide so it's super concealable. I think the main factor is that it's a TINY .45. I have the XD-S and I love it. It's my third XD pistol and by far my favorite. I've owned the 4" versions of the XD in .40 and .45. While a 13+1 .45 was cool, it wasn't the easiest to conceal.
