Trifocal-wearing granny, with my brand new XDm .40 at 25 yards. Just picked it up yesterday at the gun show and stopped by the range on the way home. Started out low, like everyone else. Also have to get used to the longer barrel. My other SA is an XD9SC, which I used for my Defensive Handgun class. Muzzle flip is a little harder to control with the .40, but I think I did OK.
