Silly question but have you checked the sights to make sure they are properly aligned?
Glad to hear it worked out for ya. Whoever sugested you drift the rear sightUpdate: I decided to forego having other people shoot my Sig and decided to drift the sites. I moved them to the right, like someone said, about the width of a CC. That did the trick. I now hit where I'm aiming and I'm a happy camper. I had a great time shooting the 200 rnds down range and can rest easy knowing it was the gun and not the operator.
I'm off to the Sig Academy next week for a course and plan to take my 226 SAO.
Thanks again for everyone's input. It saved me from selling a very nice HG.
