I have read a lot of the history on here about the 92fs and why it was chosen for the military.I was wondering what year they were first introduced and how can you what year one was manufactured. I recently purchased a 92 fs american made and have been very pleased with it. Why are there so many different names for the same 9mm round? Is there any difference in a 9mm Luger and a Parabellum or 9x19.
