In the novels preceding Dr. No, Bond uses a .25 ACP Beretta automatic pistol carried in a light-weight chamois leather holster, however, in From Russia, with Love, in the draw, the gun snags in Bond's jacket, and, because of this incident, M and Major Boothroyd order Bond re-equipped with a Walther PPK and a Berns-Martin triple-draw holster made of stiff saddle leather. He continues using this pistol until John Gardner's License Renewed, where he uses different weapons, choosing the ASP 9 mm in later books. According to Gardner in the novel for License to Kill, the Walther PPK is not Bond's favorite weapon ( note - The PPK was the gun that failed during the attempted kidnap of Princess Anne ). With Raymond Benson, Bond begins using the PPK again until being updated in both the film and novelisation Tomorrow Never Dies with the Walther P99.
