Long time since I read those novels!
Looking online, they say 007 carried a Beretta 418 in .25ACP at first.
Then a friend of Flemings wrote to him that 007 needed to be up-gunned to a Walther in .32ACP!
Not much of an up-gunning. But heck, everyone shot with either gun fell dead in their tracks! Maybe he only made head shots?
Only in the movies did 007 get outfitted with a more sufficient caliber, and in the most recent movie you would not believe the mayhem from sophisticated firearms. Bad guys still fall immediately, like before.
