The shotgun is actually a WINCHESTER MODEL 1300 DEFENDER, not a Mossberg 500. (You can see the difference mainly in the trigger guard.)
I know, because I am working on Alan Wake's IMFDB (Internet Movie Firearms Database) page right now. Someone could change the info on the page. I do not wish to intervene with your wiki. Thank you. 212.108.204.5 17:45, February 28, 2012 (UTC)
EDIT: The last sentence may sound that I dont care about AW, but that is not what I meant. Sorry if I was unclear. 212.108.204.5 17:49, February 28, 2012 (UTC)
