CZ .22-
I know what is in the book. I read the whole Bond series in my teens, and still have many. He also said that the barrel of the Detective Special was "sawn". He evidently didn't realize that snub barrels were MADE that way, or just liked the hyperbole.
I do think that looks played a large role in the guns chosen. He liked style and wanted to suit a literary "image".
The Army Special is the gun that was renamed the Official Police in 1926. It was made in .38 Special, and I think, in .32/20 and .41 Long Colt. If you go to:
www.coltforum.com and ask, someone may post a photo. Fleming owned an Official Police .38, given to him by Bill Donovan, head of the OSS. He posed with it on the cover of some of the paperback editions. Ironically, he also owned a New Service,and could have just read the lettering on the barrel. I guess he went from memory, and goofed. Likely, the gun was at his apartment in London, when he was writing in Jamaica, which was then a Crown Colony, and safer than it is today. He had an estate there, and that is where he wrote the Bond books, while on vacation from his newspaper job.
He wrote that the Beretta had a "taped" grip. This was to depress the grip safety and to make it thinner than if he'd left the grips on, but was silly. The grips weren't that thick, and the tape wouln't reliably hold the grip safety down. Tape stretches with use and age. Better to have had the grip safety pinned.
The Beretta didn't jam, I think. Rather, the silencer stuck in his belt or in the shoulder holster when he tried to draw and shoot Rosa Kleb, a KGB agent. She kicked him with a shoe that had a poisoned blade in the toe, and he nearly died. The PPK would have probably also stuck in his clothes or that old chamois holster, whichever it did. But the PPK had a double-action first shot, and was more powerful, although those I've seen shot weren't terribly reliable. An article by a German in a gun magazine said that German police figiured that theirs' averaged a jam per 50 shots. That was probably one reason why they shifted to 9mm guns, beginning in the 1970's, when shootings became more common, especially against terrorists.
