Some Berettas have been produced with the sights painted in the Von Stavenhagen pattern, in which there is a vertical white bar centered under the rear notch, and a white dot on the front sight. It is aligned by “dotting the i” with the rear bar forming the body of the letter and the white circle up front comprising the dot.
If memory serves me right, the very first Beretta 92 I shot (back in November 1989) had this sort of sighting setup.
