I took the gun back and had the sights moved .021 in. to the right and the gun shoots fine.
I have CT sights on a couple of my Sigs and after I checked the iron sights to the laser bore sighter, I just turned on the CT laser and moved the dot on the CT to be coincident with the boresighter and I am good to go.
Just something to think about. It should be a simple matter for your local gunsmith to change the sight height to fix your problem as long as you are sure what the problem is.
