So if I buy a gun that says 9 mm luger on it, I can safely use 9x19?

So why doesn't it say9x19?

9X19 is a bit more modern marking, 9MM Luger has been around for 100 plus years....just different nomenclature for the same thing.

9x19 Parabellum and 9mm Luger is the same.

Not to be confused with 9mm Makarov, or 9x18

Or 9x17, which is .380 ACP. But yes, 9x19 and 9mm Luger are two different names for the same thing.

9x19mm, 9mm Luger, 9mm Parabellum--same cartridge.

It's ironic to me that we can use the above three names interchangeably and people tend to know what's being talked about without any drama. But if you talk about a .45 Long Colt, certain folks will have a coronary, spluttering how it's ".45 Colt" and how God kills a puppy every time someone uses the name ".45 Long Colt". Sorry for the tangeant.

Because.

European (9x19) vs US designation.

Europeans designate cartridge by the bullet diameter and case length.

For example the US 38 Special is designated 9×29R. Bullet diameter, case length, and R to denote its a rimmed cartridge.

Over the years many cartridges have had minor name changes. Especially when coming from different countries.

For example 30 WCF and 30-30 are the same. Winchester originally called it 30 Winchester Center Fire (WCF), but when Remington started chambering rifles in it they didn't want to stamp the word "Winchester" anywhere on their rifles so they renamed it 30-30 and that name stuck.

In some countries 7X57 is known as 7mm Mauser and 275 Rigby in others. Same cartridge

280, 7mm Express and 7mm-06 are all the same.

Don't forget 9mm NATO. All the same.

223 Remington and a 5.56 NATO or 5.56x45 people lose their cool because they actually are not the same internally but they are externally.

9mm Kurz 9mm Corto 380 9x17
32 short 32 S&W
308 7.62 nato

there’s a whole bunch with screwy names that end up being the same, at least functionally.

I spend at least an hour on this subject alone when teaching new DDAs about firearms, specifically the 9mm, .380 ACP and .223 cartridges (All are very common cartridge cases to find at shooting scenes.)

While the plain-Jane European style of naming cartridges by millimeter dimensions and case style is rather blah, it is a lot less confusing to our beginning gun enthusiasts than the willy-nilly traditional American method.

Stay safe.

What is the difference? Can they be used in the same guns?

9mm x 19 = 9mm Lugar = 9mm Parabellum = 9mm NATO

Are we really doing this?
