    You will need a sight pusher. That is the easiest way to move the sights. My 938 is dead on from the factory.

    Is your "long green" sight a plastic light-pipe?
    If it is, you need to be very careful when you move it. The green light-pipe is fairly fragile.

    Bring with you to the range:
    1. A short piece of very clean 2x4,
    2. A drift-punch made of either brass or plastic (not steel),
    3. A small mallet or hammer,
    4. A helpful friend, and
    5. A sharp-pointed, steel scratch awl.

    First center the sight as best as you can. Have the helpful friend hold the pistol flat against the 2x4 on a solid bench. Place the drift punch against the base of the sight and then tap the punch gently with the hammer until the sight is centered.
    Now, mark that center position by making one short, continuous mark on both the sight base and the top of the pistol, using the scratch awl.

    Build-up a pad of useful height on the bench-top, using jackets, backpacks, or wood. Brace the pistol on that, and very carefully fire three shots using your best trigger, breath, and grip control.
    On the target, find the center of that three-shot group. Put pasters or tape over the three holes. Figure out in which direction you want the front sight to move, to better center the group. Remember that a front sight moves in the direction opposite to the way you want the group to move. (Moving the sight to the right makes the next group move further left.)
    Have your friend hold the gun down. Gently tap the sight just a little bit in the correct direction. Then fire another three-shot group.

    Did the center of the group move to the centerline of the target? If not, do the gentle tapping procedure again. Use the scratched marks as an indication of how much you are moving the sight. (Do not make any further scratch-marks. The one central set is enough, for indication purposes.)
    Fire another group. Is the center of the group better located now? If not, continue the procedure.
    If you go too far, turn the gun over, and tap from the other side.

    Easy, huh?

    Maybe it's just personal preference, but I like to have my front sight centered. Then all of my windage adjustments are done by moving the rear sight. That's assuming the rear sight is movable.

    The system I suggested works also on the rear sight...but you need to center the front sight first.
    Then, if the gun doesn't shoot to center, adjust first the rear sight a little, and then the front sight a little, and so on, until it shoots to center.
    By adjusting both sights, you won't end up with one of them way off-center and looking weird.

    Remember: Move the front sight in the opposite direction; move the rear sight in the same direction.
