In my experience, Berettas use a different sight alignment than most other handguns. The front sight post should be centered but above the rear. This in contrast to my sig p226, which expects the dots aligned level.
Could also be your grip...for me I noticed the PX4 shot low until I really paid attention to my grip and in particular raised my strong-hand thumb.
