First Glock and question about different sights

[HighLander51]

Can you elaborate.

After gunsmith installed the night sights...it shoots with a 6 O'clock sight ailment, which I don't like because it seems unnatural to center if mass sight alignment. My brother verified my suspicion. Appears the sight was grinded down too much. I am positive it was center of mass sight alignments, but gun smith returned them with 6 O'clock sight alignment.

He didn't grind the front night sight (or shouldn't have) it's just too short. There should be an option for a taller front that will lower the POA
