To be technically correct, it is:Oldgringo wrote:A .380 is a 9mm kurz (short).
A 9mm is a 9x19 or 9mm gross (long)
Just sayin'.....
9x17mm 9mm Kurtz (German for Short) or aka .380
9x18 9mm Makarov
9x19 9mm Parabellum or Luger
9x21 9mm Largo (Spanish for Long)
Never heard 9x19 called 'gross'. What language is gross for long?
