um... the .22 mag is alot older than just the 1960's...
it is ALMOST the same exact cartridge as the old .22WRF, which was available in the late 1800's... (as witnessed in the factory chamberings in the Winchester 1890 pump-action rimfire...)
the .22 mag has it's place in personal defense, (ultra-small handguns) but the 9MM is better, if you have the room for the gun that uses it.
