Door too low on striker

On my '74 Swinger, the passenger door looks perfect when closed but hits the striker about 1/8" lower than it should. It lifts up into position as it rides onto the striker. This makes the door a bit hard to open and shut (my wife and kids complain about it). To my novice eye, the hinges don't seem to have any play in them. Is it worth trying to adjust this or will I more likely make it worse?

Leading edge looks good.

Trailing edge is close. This pic shows it as the door is closing, just before the door engages the striker.IMG_2492.JPG
Here's another angle of the door just before engaging the striker.

When the door is closed, the trailing edge lines up perfectly with the quarter panel.
