Well, let's go back to the beginning - -
- -Shall we?
In the original book,
Casino Royale, Bond carried a Beretta .25, "with the sawn barrel and the taped grip," and also had a "long barreled Colt." The Colt was his car gun, and the .25 was carried in a "chamois shoulder holster." Really, most of the the guns "Bond SHOULD have had... " being mentioned are rather large and heavy for deep concealment by a true spy, as opposed to an assassin.
A book or two later, I think it was in
Dr. No, Major Boothroyd counsels Bond on a more powerful piece, and mentions evaluation of several handguns. This included the Steyr M38, another 7.65 (.32 ACP.) I've always smiled at the declaration that the .32 cartridge is "a real stopper," and, "hits like a brick through a plate glass window." Well, compared to a .25, I guess it's pretty staunch. Again, we must remember that most East-of-the-Atlantic handguns were of pretty modest size and power. A 7.65 was a perfectly acceptable police sidearm, and many military officers felt the same.
The Italian Navy used the 1935 Beretta in 7.65, while their army had adopted the bigger, more brutal 9 mm Corto (.380 ACP) the previous year. As to the Germans, they adopted the rather substantial 9x19 mm early in the century, surely, but it was as a replacement for the old, large bore black powder revolvers. One of their more notable aerial warriors, Colonel Hans Rudel wrote of being afoot in enemy territory armed only with a 6.35 pistol. He survived more than one shot-down, and apparently never opted for a larger handgun.
I guess all this historical rambling is merely aimed at these considerations: What was Bond's mission? Would he have felt the NEED for a larger pistol for daily use, as opposed to special circumstances? What was the prevailing attitude toward handguns in the time/place for which Fleming was writing? And, do the movies bear much actual relationship to the novels Fleming wrote? Remember, many of the above comments are based upon what was depicted on the screen, and NOT in the books.
Really, the PPK wasn't a bad choice given the era. I might have chosen a Remington Model 51 for him, and a five-shot S&W .38 would have served very well, especially in the early Airweight versions.
Anyway, this is all a lot of fun.
