    Yes it's confusing ! Invented in Germany more than 100 years ago . 9mm Luger , 9x19 ,9mm Parabellum are all the same . The term 9mm though commonly has become a name for it also ,really only refers to bullet diameter . There are MANY cartridges using a 9mm bullet diameter so saying '9mm' is not sufficient !!

    They are the same. There's an old cartridge called the 9MM Largo which is not and sometimes the .380 auto is referred to as the 9mm short.

    There are a lot of different names for the same cartridge, in this case the 9x19 or "Luger" of German origin. The only changes worth noting is that the pressure varies to some degree so, older firearms shouldn't be used with high pressure modern rounds. The over pressure SMG rounds are really meant for blowback SMGs but, can be used on a limited basis in modern high quality 9mm handguns.

    Never shoot unknown ammunition in any firearm. Surplus that has been stored for decades can have erratic pressures as grains of powder get fractured and turn to dust. Instead of a nice burn, you can get a detonation.

    Watch out for 9x18 and 9x21. 9x21 is more commonly used overseas.

    With former Russian cartridges, the bore diameter is measure differently. Ruger used .308 barrels for their 7.62x39 rifles which was a problem for many. Measuring the lands versus grooves and mixing it up can ruin your day.

    Plus there is 9mm Browning Court, which is .380.

    But, as everyone else has said. 9mm, Luger, and Parabellum are all the same thing.

    9mm NATO is loaded to Euro spec (not SAAMI spec) and because of that, is a little higher in pressure than the stuff we get here. You won't find much of it outside of Winchester Ranger RA9124N (I think that's the sku number). It is not quite +P, but definitely hotter than the watered down range ammo stuff you get here in the States.

    Nato spec 9mm isn't too hard to buy on-line from reputable sources. You can tell a difference from the cheap range loads most people shoot with the recoil and noise.

    That and the headstamp is marked with the NATO cross.

    You mean "kurz", right? "Kurz" is German for "short" and is used to distinguish between this auto round and 9mm Luger/Parabellum/NATO/9x19 etc.

    Not that one is likely to run into it but Federal also made a rimmed 9mm cartridge.
