Walther PPK
The fictional secret agent James Bond used a Walther PPK in many of the films and novels: Ian Fleming's choice of Bond's weapon directly influenced the popularity and notoriety of the PPK. Fleming had given Bond a .25 Beretta 418 pistol in early novels, but switched to the PPK in "Dr. No" on the advice of firearms expert Geoffrey Boothroyd. Although referred to as a PPK in the film adaption, the actual gun carried by actor Sean Connery was a Walther PP.
