I've owned an FNP in .45 ACP for several years now. It's a Duty sized gun, with the weight and heft of a Duty Gun. That said, it's soft shooting, and extremely accurate. Just about everyone who's hands fit it were quite taken by it's performance.
The XD is the XD. I have never found them to be "special" in either looks or feel. They are, however, accurate and reliable. My friend owns one, and we shoot each others guns regularly.
Handle the guns, see how they feel. Try to shoot them BEFORE purchasing anything.
