What we call "380Auto" is what the Europeans call "9mm Browning Kurz". It's really more accurately called 9x17mm, because it does use a 0.355 bullet, but the case is 17mm long.
I recently bought a 32ACP, which is what the Europeans call "7.65mm Browning". "
A prophet is never honored in his own country." So I guess the Europeans simply hold JMB in higher esteem.
