I picked up a copy of Jeff Cooper's To Ride, Shoot Straight, and Speak the Truth. The copyright on the book is 1998, but I think it is just a collection of earlier writings - so I don't know when the following was actually penned. In a section regarding military pistols, he talks a bit about the pistols used throughout history. He certainly has no love for the 9mm... He calls the Colt 45 "the world's best service sidearm."
He goes on to discuss "New Ideas" and says this; "The essential weekness of nearly all new military pistols is that they continue to be made for was has been long proven to be an unsatisfactory cartridge, the 9mm Parabellum. The best of the new official designs in the Czech 75, and if that weapon were available in a serious cartridge it would be the brightest thing on the horizon."
That begs two questions. I wonder what Cooper thinks of the latest 9mm cartridges and if he still considers it unsatisfactory. And assuming this was written before the 97B was made, what does Cooper think of it?
