Really? Any documentation that you can reference?
Browning Hi Power
Page 25, Browning Hi-Power manual:
FIXED SIGHTS
Some Hi Power pistols are equipped with a fixed front sight blade and
a drift adjustable rear sight. No adjustment of the front sight is
necessary. Rear sight adjustment is a process of trial and error.

Kahr K9 manual, page 15:
Both the front and rear sights are held in place
by the tight fit of the sight to the dovetail. On
the CT, CW and CM Series the polymer front
sight is pinned into the slide and cannot be
moved. Windage (side to side) adjustments are
made by pressing the rear sight in the direction
that you want the bullet placement to move.

Name the Glock, I'll send you a gazillion links to the manual that will tell you how to adjust the drift adjustable rear sights.

Care to try again? Until you get down to the pocket pistol category with the rear sight groove machined into the slide, every serious combat (military/police issue) semi-auto will have drift-adjustable rear sights.
