I have an XD 4" in 9x19. It's a nice little gun. Points a lot like a 1911, the controls are good (I like the ambi mag release), and overall, has some features up on the Glock (steel sights, dovetailed front, grip safety, ambi mag release, easier takedown, etc.). The Glock has a more proven track record, though, so I'd go with whatever one fits your hand better. I like my XD, though, and don't see myself getting rid of it any time soon.
