What's the difference between 9mm Luger, 9mm Parabellum, 9x19, 9mm+p, and any others that I may have forgotten? Can you fire any of them out of any 9mm?

9mm Luger = 9mm Parabellum = 9x19
9mm+p is the same as the above, only loaded to a higher pressure than specs. They should only be used in pistols rated for +p ammunition.
All of the above are the most common form of "9mm". There are plenty of other calibers that are known as 9mm as well, such as 9x18, 9x17 (aka .380/9mm browning/9mm short). There are many others which I can't name off of the top of my head.
What type of pistol are you asking this question about? As I said, 9mm Luger, 9mm Parabellum, and 9x19 can all be shot out of the same pistol, but definitely don't go trying to shoot .380 out of that pistol or vise versa.

I've got an Astra A 100 and I've always shot 9mm Luger out of it. Never had any problems with this weapon. Was just making sure I was shooting the right stuff out of it. I appreciate any information you can give me as I'm not real up on autoloaders. I did just buy a RIA 1911 in 45 acp that I'm really looking forward to shooting when I get it. I just bought it on Sunday so I probably won't see it until next Wednesday at the earliest. But I figger the 45 will only shoot 45 acp so there shouldn't be a problem. I've put dies and toolheads for my Dillon press on my Christmas list so I can shoot this thing often. It felt really nice in my hand.

Ok, so 9x19, 9mm luger, and 9mm parabellum are what you're looking for. They're all the same. As for the +p ammunition, you'll have to look into that further. The manual should say whether or not the pistol is rated for +p ammunition.

Exactly it is just different names for the same thing like car, automobile, and sedan.
9x19 = 9mm Luger = 9mm Parabellum. They are exactly the same round just different names.
9x18 = 9mm Makarov because the Soviets ALWAYS have to be different if they used the same ammo as someone else it would be the end of the Soviet Union... oh wait...
9x17 = 38 Auto (rarely is .38 Auto called 9x17 but that is essentially what it is).
If someone is talking about ammo for their "nine" likely it is 9x19.

The 9mm Parabellem was created at the request of the
German Army. They liked the Luger Pistol but the original 7.65
Luger cartridge was a bottlenecked design. By making it a
tapered wall cartridge the caliber ended up as 9MM. Sidenote:
George Luger created the Luger pistol adopted by the German
Army in 1908 thus it was designated the P-08. Lugers
were made by DWM and Mauser among others.
The metric/European designation is 9x19. 9mm NATO is the same
cartridge to NATO loading. It has become popularly referred to as
9mm Luger for the P-08 that it was originally chamberd for.
x19 refers to the height of the case.
A .40 S&W metric is 10x21
A .45 ACP is rounded for convenience, 11.4x23?
I'd have to do the math, and coffee calls.
9mm Markarov is 9x18
.380 ACP or = 9x17 aka 9mm "Kurz' or Short
THe latter two are fired at low pressure as they
are used in blowback actions. THe 9MM Parabellum
is higher pressures 35,000 CUP and 9MM Luger +P
is 37,500? or something like that.

Bear in mind the Makarov is really a 9.2 x 18, firing a .364" bullet instead of the .355" common to nearly all other cartridges of 9mm caliber. Not interchangeable with anything I know of.
That's .380 Auto.
The .38 Auto is a far different cartridge, a true 9x23SR in European parlance.

357sig is another 9mm.

Ha! Once we've beaten this one to death, can we talk about the different 45 calibers?

All I know about the 9mm Parabellum is that in JHP form it's a whole new breed of cat compared to its bad old days in the 80s.

.38 Super is supposed to be .356, but .355 bullets will also work.

Two truly "hot" 9mm cartridges are the 9x23mm Winchester and the 9x25mm Dillon. Both of these rounds stem from attempts to make more effective 9mm rounds for practical shooting competitions. While they are potent 9mm cartridges, neither has gained any great following, nor does that trend seem likely. They do merit discussion here since they reveal just how broad the 9mm family tree is.
