It usually takes myself a couple outings with a pistol to be satisfied with zero. Initial slow fire zero at 25 yards and then 25 yard to 50 yard Bill Drill stuff with a draw out of holster at speed. When I just shoot slow fire without a draw at speed the grip is perfect which maybe only happens 25% of the time with the draw. I am more concerned with rounds staying centered around POA shooting at a rate where the sights are just settling in.
