Joshua's Pistol Whippin' .45
As a companion, Joshua Graham will use this weapon when prompted to use Melee Weapons. As the name implies, it is Graham's unique .45 Auto pistol, A Light Shining in Darkness held by the barrel and used to "pistol-whip" enemies with the butt end of the gun. Its special V.A.T.S. attack is called ‘lights out’. It is considered an improved holdout weapon. It takes appearance as a rolling pin in your pip-boy.
