 The animation is sufficiently detailed to identify some of the guns  used; the pistol used by Vincent Volaju on the train is identifiable  as a Strayer Voigt Infinity, chambered in either .45 ACP or .380  Browning, and the submachine gun fired into the weather control  center ceiling by Faye Valentine is identifiable as a Heckler & Koch  MP5K, chambered in 9mm. Fayes pistol is a Glock 30: the model  number is clearly visible when Faye shoots the game in the arcade.  (The Glock 30 is chambered for .45 ACP.) Spikes pistol is a IMI  Jericho 941, though the movie does not give enough clues to identify  what round the pistol was chambered for. Jets pistol appears to be  a Walther P99, but lack of detail makes identification and  chambering difficult.
