As a young boy, I was reading the James Bond novels in the mid-60's. By the mid-70's, I finally had some handguns. One of my first auto pistols was a S&W Model 39-2, which I carried around on many of my early adventures. I always thought the PPK in any caliber was pretty short on stopping power, and so "in my own mind" I had James Bond armed with a Model 39 in 9 m.m. . Not the best maybe, but the 39 hit the civilian market in 1955 I think. The first James Bond novel was published in 1953 I believe. If Boothroyd had simply skipped over the pocket pistols and given 007 a Model 39, Skaramanga's line in "The Man with the Golden Gun", who in the book carried a gold plated Colt Commander in .45 IIRC, asked Bond what he carried to which Bond replied: "Walther PPK, 7.65 Millimeter."
Skaramanga's reply of "Yeah, that's a stopper" would not have seemed so incredible had it been a Model 39 in 9mm.
That original Model 39 got sold off around 1979 or so, I used the money to buy the 1911 I used through my early days as Director of IPSC/Manitoba. That same year, I was in Deming, New Mexico at the M.M.C. Sight Company shop which at that time was located in Deming, to get a new set of sights put on that very 1911 by the in-shop techs. On a desk was the Model 59 that Skeeter Skelton, a gunwriter for "Shooting Times", who lived in Deming, was doing an article on. "Shooting 10,000 rounds through a Model 59!". They were just over 5,000 at that point. I did not meet Skeeter, but had a great party with the M.M.C. sight crew that evening. Skeeter later noted that his Model 59 frame broke at the slide-stop entry hole around 9,500 rounds but continued to function to finish the test. I already knew that could happen as the Model 39 I had sold that very year broke in the same location after only a few hundred rounds in the hands of the new owner. Oooops. I had sold it cheaper than I wanted to because I needed the money, but I sure didn't think it might break. Oh, well.
Years later, Colonel Phil Maher, the U.S. Consul in San Miguel dug me up a Model 3904 to "bring to the party" when I would sometimes go to help him on consular stuff. Or more actually, he did any actual "consular stuff", but would invite me only when something might go testy on him as sort of a backup. I used to refer to those jobs as "Colonel work" rather than Consular work. He had been dismayed when I showed up the first time to a potentially bad situation with only my 5-shot Model 49 snubby, which was all I had at the time. He got me the 3904 -- as he had my snubby -- from the effects of an American who had died naturally and I took a photo of it along with his 669 on my couch the night he brought it over.
Because he had a letter on Consular stationery saying I could carry the 3904 while working on "Consular business" that was co-signed by the General at the 16/A Military Zone in Sarabia, Gto., I carried that 3904 all over Hell's creation. Generally I used a Galco "Original Jackass" rig, but I also had a Galco "Air Marshal" inside-the-pants holster for it. I had the guys at the Queretero Custom Shop apply a spray-on finish to the frame that they got from Brownell's and it held up amazingly well. I don't think I did much else to it, although I did convert it to .380 Cal along the way because there was no downside to doing so. .380 Cal is about 9 mm +P in power, being a 142 grain LSWC bullet at 1020 - 1030 fps from a 4-inch barrelled Glock or 3904.
I broke a trigger bar on it around 2003 and had to get one from Numrich and get it into Mexico. Not hard then, not hard now. So the design has some flaws: the broken trigger bar completely ties up the gun. You cannot shoot it, you cannot dislodge the sear and hammer. But I fixed it. I sold the gun and holster to a friend when I left Mexico. However, I carried it everywhere inside Central Mexico: Mexico City, Guadalajara, on a sailboat between Puerto Vallharta and Mazatlan and all around both towns. Plus everywhere in the State of Guanajuato and also much of Queretero and all the way to Pachuca, Hidalgo several times for meetings at the head office of the Ice Cream Store chain I was a part of. I have always felt that James Bond should have had a Model 39. The gun has it's flaws, but I'd still take it over a lot of what's out there. And I don't mean for range work. I mean for Colonel work, or any reasonable facsimile thereof. Bond would have done well with one as well I think.
In the book, Boothroyd mentioned that he had fired 10,000 rounds through a variety of pistols, I believe. Not just the PPK. So the Model 39 of the time would have survived his tests I think, since he wasn't firing 10,000 rounds through just one pistol. I think they beefed up that area around the slidestop entry hole by the time the 3904 came out. Mine fired easily more than 10,000 rounds and never cracked. It also never jammed. But that broken trigger bar....one doesn't forget something like that, either.
