SCP-3118 is a Beretta M9 pistol. Its anomalous effects activate only when it is used to fire a bullet at the cranium of a human being. Using the object to fire a bullet into other parts of the body will result in standard gun-inflicted trauma and not activate its effects unless the bullet also passes through any portion of the cranium.
A bullet fired in this way will dematerialize upon contact with the cranium, and instead of an exit wound and ejecta, SCP-3118-1 will emerge from the far side of the cranium along the bullet's path. SCP-3118-1 is an exact recreation of something the subject has eaten for lunch at some point in their life, including containers and utensils used to consume the meal. Food items consumed in part will manifest as they would have been served to the subject. Only meals eaten between 11 AM and 3 PM local time will be recreated this way.
XD, your puny CI computers cannot even properly pull up a file.
