I've been thinking long and hard about one of these for carry lately. I currently have a CZ P-01 as my carry gun, but I'm sort of phasing out 9mm; nothing against the round (which has its strong points, to be sure), but I have just been enjoying shooting .45 ACP so much lately.
I don't want to carry a Sig P220 because it seems to be the size of a small boat anchor, and I'm none too keen on carrying a 1911 because they weigh more than I care to have strapped to my body for hours on end. That leaves me with the plastic guns. Glocks are a no-go because, frankly, even the thought of holding one makes my hand uncomfortable, and although the M&P feels good in the hand, there's something about it that doesn't quite match up with me (maybe its that the trigger feels a little flimsy). Thus, all roads seem to lead to the XD, or, at any rate, it's the only other gun I would seriously consider. I just might see one of these in my not-too far off future....
