I am a pretty well trained shooter, learned marksmanship in the Marines, etc. I don't really have bad shooting habits.
For whatever reason, I shoot XDs and XDMs better than anything else. I don't think the design is any more accurate than Glocks, Sigs, M&Ps, 1911s, etc...but I can't argue with the results on paper. I've shot them back to back enough times that I'm convinced. It must be the way the trigger breaks
