Make sure the slide cap screw (on the left side) is tight. Otherwise, it might be one of those "start replacing parts" deals.

Thanks Paul

Your problem is likely caused by the technique you use to adjust windage.
The rear sight is spring-loaded in the windage axis. To properly adjust windage, you should turn the windage knob clockwise to over-correct windage, then turn the knob counter-clockwise to the correct windage setting. This technique removes all slack in the windage mechanism.
If you crank in too much windage, then you need to turn the knob clockwise to over-correct again, then start over turning the knob counter-clockwise to the correct windage setting.
The rear sights on National Match rifles were precisely made and carefully fitted to remove the slack for precise adjustment in both directions. But, service rifle sights were not so carefully made and must be adjusted in one direction only for accurate shooting.
Hope this helps. Good Luck!

That is the spring tension JB described. They all do that.

Johnny Peppers is right. That's why windage should be adjusted from one direction only, i.e., counterclockwise rotation of the windage knob. Otherwise, you'll be dealing with erratic movement caused by spring hysteresis.
Hope this helps.
