Try dropping your pistol down a little farther in your plane of vision. Perhaps 10-14" or so below eye level.

Start a 3-5 yards and use some type of human silhouette target.

Extend the pistol in front of you with a two hand hold and focus on a spot on the target. If the sight distracts you lower it a little more.

Squeeze off a slow, smooth shot and note where it hits. Too high on the target, look at a spot lower, too low, look higher.

Practice drawing it from your holster, or raising it up from low ready and find the one and two handed positions that you naturally go to and that feel most comfortable. I don't believe there is one rote position thats the same for everyone and there is a whole continuum from waist level to eye level that one can practice. However, in sudden, up close, life threatening situations your natural one handed hold position is more than likely the one you will unconsciously assume.
