SPOILER ALERT! So, wikipedia tells us that “Shortly before the publication of From Russia, With Love in 1956, Fleming received a fan letter from an author and gun collector, Geoffrey Boothroyd. He told Fleming that he admired the Bond novels apart from the hero’s choice of weapon. Boothroyd felt the Beretta was ‘a lady’s gun’ with no real stopping power. He also objected to the choice of holster. Boothroyd proposed that Bond should use a revolver like the Smith & Wesson Centennial Airweight. It had no external hammer, so it would not catch on Bond’s clothes. The Smith & Wesson could be kept in a Berns-Martin triple draw holster held in place with a spring clip which would decrease Bond’s draw time. Boothroyd also said the suppressors Bond occasionally used were rarely silent and actually reduced the gun’s stopping power . . .
Fleming thanked Boothroyd for his letter and made a few points of his own in his reply. He felt that Bond ought to have an automatic instead of a revolver. Fleming agreed that the Beretta lacked power, but pointed out that Bond had used more powerful weapons when necessary, such as the Colt M1911 .45 cal auto pistol he uses in Moonraker. Fleming also said that he had seen a silenced Sten gun during the war and the weapon had hardly made a whisper.
Ultimately Boothroyd recommended the Walther PPK 7.65 mm as being the best choice for an automatic of that size, with its ammunition available everywhere. He suggested, however, that 007 ought to have a revolver for long-range shooting.
Yada yada yada. Pea shooter. Smith & Wesson .44 for the win. What’s your fave?
