Glock 26 (9mm), 27 (.40 S&W), or 33 (.357SIG) are awesome little pocket rockets. Personally, the Glock 33 in .357SIG is fantastic...especially with a model 32 mag and an A&G grip spacer to fill in the blank area...one of the better grips systems.
The Glock has a lower center of axis/bore for managing recoil and fits nicer in my hand (personal opinion), giving me a more comfortable feel when shooting.
The Glock also has just about anything you might need for it available on-line and you can do most of the work yourself.
Bottom line is that it IS your choice...but the Glock, as a product, out weighs the XD in my book.
