Memento

Memento (2000).

(Note: As most of the film is shown backwards in the order from which they actually happened, all screencaps and gun listings are shown in the film's chronological order. This is why a character is seen using weapons before he actually gets ahold of them.)

The following firearms were used in the film Memento:

Smith & Wesson 3913 "Ladysmith"

Leonard Shelby (Guy Pearce) takes a Smith & Wesson 3913 "Ladysmith" from Dodd (Callum Keith Rennie), who used it to shoot at him. Leonard uses it through the first half of the film. (I'm not 100% sure about this one, it might be a 910 or something like that instead.)

It's a S&W 6906. If it were a Ladysmith, it would have the white grips. Also, it's not a 910 either (wrong finish and frame size). -MT2008
