Handgun ID

Hey guys, sorry if this isn't the appropriate place, I'd like to ID the gun in the picture, sorry about the quality, it's really the only one I have, I've seen this person holding it in various cosplay events and I'd like to know if its real or not and if I should be worried.

Thanks in advance for any help.
