Two out of three of the M&P pistols I recently bought had the rear sights noticeably off. The compact was way off - should have never left the factory like that. My 9, which I haven't shot but once, has centered sights. My buddies .40 compact also had his sights noticeably off center too. So yeah, it is actually amazing how many pistols come out of the plant with off centered sights isn't it. I see silver contributor under your name. Is this how you got so many posts in...trolling ? Tell me in what way your post helps me. I also see you live in California. Strike two. Go find another thread and stay away from my posts. You don't impress me. Your two cents is not welcome. Go play important forum member with some other new guy.
