Thread: is 9mm ammo 9mm ammo?

  1. #1

    is 9mm ammo 9mm ammo?

    I tried to research this, but get lost on rabbit trails of grains and velocities, etc.

    here is the situation. I am out shopping for ammo for my Beretta PX4 Compact 9mm.
    I see:
    9mm Luger
    9mm Makarov
    9mm Police
    9X18 Ultra
    9X19 Parabellum
    then it gets into the 9X21 and higher

    What is the difference? Before I ever bought a gun, I always thought 9mm amm was the same, just different weights and type (FMJ, HP, etc)

    Thanks for any help to keep me from going crazier than I am

  3. Are all .30 caliber rifle rounds the same?
    Have you compared the .38 S&W and the .38 Special?
    9x19=9mm Luger=9mm Parabellum.
    The others are all fairly rare rounds that are quite different from 9x19. This is one reason I try to correct those who simply say they are shooting a 9mm--there are a LOT of 9mm handgun cartridges, and you have less than half of them on your list. You don't even have the 9mm Browning Short/9mm Kurtz on there.

    9mm Luger/9X19 Parabellum are the same thing, normal 9MM ammuntion


    9mm Makarov/9X18 Ultra

    Are for Communist block weapons and the case is 1mm shorter than 9mm NATO (9X19) to keep NATO forces from chambering our ammunition in a captured weapon

    ocasionally you'll hear people talk about 9mm short, 9mm Browing or 9mm Kurz which are all .380 rounds

    Thanks guys.

    I am starting to think that they have so many different names to confuse us ignorant ones.

    At least you guys made it easy to understand,

    Now it makes sense why I saw the only option at my Walmart yesterday was MKE 9mm Parabellum. I tried to figure out for the longest time if that would work in my gun, because I had heard to use 9mm Luger.

    Thanks again

    But can you use 9mm Makarov ammo in a gun chambered for 9mm Luger?

    I wasn't making a case for the Russians logic I was just stating why they did it. Smae reason their artillery was 152mm and ours was 155mm

    That was actually a question. Can you use 9x18 in a gun chambered for 9x19?

    I wouldn't know but I wouldn't think so because the case length wouldn't be right

    No, the case is 1mm to short so the forward end case won't hold the round far enough back for the firing pin to strike the primer and fire the round. Nate

    Well that seems some strange logic. I suspect that the round will go in the chamber until the rim of the case stops it even though it will not completely fill the chamber. A .380 will also, but will it feed properly? Will it fire, should you try to fire it? I wouldn't.
