You have a small fast target with a pistol - yep I can see them missing. This is real life, not Hollywood where everyone hits their mark in Hollywood - at least if you are the main character.
Give these coppers a rifle and I bet they would hit him every time too. A pistol is nothing more than a defensive weapon for use against a man sized target at very close range. It is not an offensive or hunting weapon.
