"A relatively powerful handgun. It's in bad condition, but it still looks usable."
— Inventory description
In the demo, the M19 Handgun is located in the bathroom in the toilet and can only be picked up after flushing which can only be done by using the Valve Handle on the pipe first. Upon interacting with it, an animation plays where the character psychically reaches to pick it up then cocks it.
In the main game, the player finds it in the same house but it is placed in a different room. The player can find it in the room before the path leading to the attic, along with a box of Handgun Ammo and a bottle of First Aid Med. After being brought into the mansion, a broken version of the weapon can be found in a trailer outside in the backyard. The player needs to find a repair kit in order for the weapon to function again. A repair kit can actually be found outside the trailer where the gun is found in a secret area under the back deck leading back into the house
