Personally, something about the XD makes me wanna puke, but I have no functional reason for that. Just cosmetic.
I have a Glock 19 now, and at some point I'd like to own an M&P9 to compare with, but I have zero desire to own an XD.
Wait, the XDs looks makes you want to puke? Glocks are widely considered one of the ugliest handguns ever. Or so i thought.
