You say you have a laser on the gun. Have you tried a laser bore sighter that mounts in the barrel?
I think I would want to do that before I started messing with the sights.
I have a laser bore sighter and I confirm every gun I buy. I have several Sigs and none of them have required sight adjustment. I am not saying yours isn't different, but it might be worth a look.
I did put a bore sighter in my Dan Wesson Valor and it indicated the gun would shoot to the left.
It shot to the left for me as well as for two experienced shooters.
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.
In any event, good luck and get back with us and let us know what you did to fix the problem.
