The first time he shot it his shots were so far left that, like you, he had to move the rear sight to the extreme right to get his shots centered. He called me upset about it, and the next day we went out shooting together. I took a turn shooting the gun -- only to find that for me, with the sights adjusted far-right, it shot far to the right. I suggested a more hand-filling grip, he bought a set of Pachmayr Presentations, and suddenly his problem went away.

It may need to go back to S&W, but I'd have someone else try it first.
