I see nobody has answered this post, sorry for that. In this forum, we are usually fast to reply!
My advice is, since it is the sight itself, to take it to a gunsmith, to have the sight either corrected, if possible. Or have it exchanged.
I had a white dot, that was not aligned once, and it bothered the **** out of me. Then I put on Rolling Stones and painted it black. Have never regretted since. I only use the silhuett of the back sight, and with a fiberoptic front sight, it works dandy.
