Shooting tip from Bob Chow

Much have been said about front sight focus, alignment of the front and rear sights, gap size, center hold, 6 0’clock hold, sub-6 hold and so on.
However, his only tip to me before his passing was, “Bring the front sight to the rear sight!” No one else has ever mentioned to visualize as such.

It all happens at the gun.

I think what he is saying is to visualize pulling the front back into the rear sight. For dots, I try to visualize pulling the dot into my eye.
