Maybe fate led you to post in the 1911 forum??
That Mil-Spec up there is a good 'un.
On the original topic, I've had XDs and Glock and I lie the Glocks better for several reasons.
Lower bore axis shoots flatter and faster.
Trigger break and reset are much better on the Glocks.
Less parts and easy to detail strip.
Tons of aftermarket stuff (even though I don't have any).
Spare parts are cheap and available all over the internet.
That many cops and militaries can't be wrong.
The XDs are good guns too, so I'd get whichever one ya'l shoot the best.
