The XDM has the advantage only in 40SW. The capacity had been an issue in the 40 for some time. If you want capacity then go for the XDM9. I perfer the xd9tac because of the abillity to use 1911 springs to tune the gun for my handloads. I don't know if the XDM can do this. As far as "match grade" goes...I take that phrase with a grain of salt when refering to a production gun or combat handgun(which this is). The XD is a combat pistol and needs significant trigger work in order to be competitive.
