Springfield Armory sent me a higher rear sight in order to change my XDm to shoot point of aim instead of six o clock hold. I had my rangemaster install the rear sight. My rangemaster and I test fired the weapon at 7,10 and 15 yards. All shots were about 2 inches higher that my point of aim. I will call Springfield tommorrow and ask if I can send the XDm back to them (any pay any fees) in order for them to test fire and make adjustments for the gun to shoot point of aim.
