First, you need to learn to raise the gun to your cheek, not your shoulder. Do this in front of a mirror, with a gun you have triple-checked to be sure it's unloaded. Stand facing the target, which, in this case, will be the reflection of your right eyeball. Your feet should be barely shoulder-width apart, your left foot about half a step in front of the right and pointing at the target. (I am assuming right-handedness throughout. Left-handers, you know the drill; reverse these instructions.) Hold your gun more or less horizontal to the floor with the butt tucked lightly under your arm.
