I just got an XD .45 ACP. I am a confirmed "Glock Guy", BTW. I have four Glocks: 17,19,23 & 37. Glock 21 is just a tad to thick to be comfortable. I actually love the .45 GAP model 37, it fits my hand but ammo...getting hard to find in my neck of the woods!
After shooting an XD at my gun club in .45, I found that it fit my hand. It was comfortable and accurate too. Recoil is not a factor with me, so I'm not including it. Take down is simple, very Glock like. Even with 14+1 it is comfortable to carry, altho finding decent leather for it wasn't as easy as other pistols. My buddy Sam Andrew's of Andrew's Leather in Gainesville, FL had one on hand and that problem was fixed. Carries nice too, altho that might be Sam's design.
All in all, I really like the XD and am happy with my purchase.
