yeah it's different when you know it's a movie but this clip is pretty nasty, there isn't a blood splash onto the wall behind him but it shows blood pouring from his nose and everything once he hits the ground...
I think it was a .357 magnum pistol. Less than a minute before, he hands out a suicide letter and an organ donor certificate to people who were unaware of what they were yet and then he had the pistol hidden in an envelope.
