I am getting ready to purchase my first hand gun and it will be either the 9mm xdm 3.8 compact or the 3.8. Except for the compact being about a quarter of an inch shorter, what's the difference? Does the compact come with both 13+1 mag and 19+1? Is that the only other difference between the two guns? Smaller mag for concealed carry and larger one for range shooting, etc.? If that is the only difference, wouldn't that make the compact more versatile? What about accuracy between the two guns?
