I sight in at 20 meters. Many sight in at 25 yards. Usually you will be defending yourself at 7 yards or further. Seven yards is the closest you want to let anyone with bad untentions approach you before you shoot. I shoot from 7 to 200 yards with my 9mm and 124 grain RWS FMJ. It doesn't hurt to know how to hit something that far away just in case. We have a steel humanoid silhouette set out there. Besides to hit the longer range targets it forces you to aquire a perfect sight picture and trigger squeeze. It makes shooting at 7 yards pretty easy.
