Never Say Never Again

The weapons used in this movie are:

Walther P5

Rather than his traditional PPK, Bond uses the more modern P5 in this film, presumably to appease the manufacturers, who were trying to promote a new pistol. Of interest is that in Octopussy, the official James Bond film released in 1983, as opposed to this attempt by Warner Brothers, Bond also uses a P5, having "mislaid my PPK".

H&K MP5

The MP5's used by Largo's men have straight magazines indicating they are old spec.

M3 Grease Gun
