Beretta 92FS Inox

Ethan Mars uses a Beretta 92FS Inox in the game Heavy Rain. It is sent to him after his son is kidnapped by the Origami Killer.

(Actually, I'm certain this is the same weapon that Scott and Jayden use - identified as a Beretta 90 Two above. I think they all have that extra bit under the barrel)

Sig Sauer pistol?

Blake uses a silver pistol that looks like one of the P22-something guns. He can be seen swinging it around when chasing Ethan in the subway and at the motel. The same weapon is also used to kill Paco. If examined by Jayden in ARI it is described as "Serena gun" (Serena might be the name of the nightclub though) and apparently chambered in .45 caliber rounds.

Small handgun (a Makarov?)

Used by Madison in the nightclub and the elder Kramer in his mansion during Scott's assault.

Colt M1911 (or variant?)

Used by Paco and Nathaniel (the ludicrously Christian suspect Jayden)

Unkown Revolver

Mary Smith uses an unknown revolver in an early tech demo of the game, though based on a visual comparison I'm gonna say it is a S&W Model 625. Feel free to correct me if I'm wrong, though.
