It would depend on what agency the "Bond" type is working for.
Most probably a SIG 228. DSS, uses them almost exclusively. AS do Military Intel and army/Navy CIS(DSS=Diplomatic Security Service) out of the country so would the Secret Service, and FBI. (the SIG 228 was an issue weapon in both agencies at one time.)
What ever they use it will be in 9mm. Most available cartridge, world wide.
I would advise a Browning/FN high Power type weapon or a P35 knock off. Found in more countries than any other handgun. Made at various times in of course Belgium, France, Canada, UK, Eastern Europe, South America, Spain and the Philippines. Of course in 9mm.
I do Know the SOG teams in Laos and Cambodia used cleaned P35's on their missions.
go figure.
