I haven't shot the XDM in 10mm, but it was nice in .40S&W
on the glock there's a ton of aftermarket to do about anything you want with it, not sure about the XD but if it runs the big stuff right out the gate it might just be a better no hassle option
This is what I like about Glocks. Plenty of accessories and after market stuff. I've shot an XDS in 40 but not a fan of the grip safety. Good gun though and glad to see 10mm is making somewhat of a comeback.
