I have found the easy way to remember this is to:

1. Hold the gun in your left hand.

2. Looking at the windage screw on the side - turn it toward the right to move right - toward the left to move left.

3. Still holding the gun in your left hand, turn the top of the gun toward your body so you are looking at the top of the sight.

4. Turn the elevation screw up (left) to move the bullet up and turn the screw down (right) to move the bullet down.
