Please forgive a silly question

No mention of the .38 New Police yet? A .38 that was actually .36-ish and the only reason it existed was Colt didn't want to use the name .38 S&W for the caliber in their revolvers.

Yeah, it can get confusing, especially with the 9mm or .38, where there are so many variations.

Great answers, you guys are so smart.

AKA 9x17...

9MM Browning, 9MM Short, 9MM Kurz, 9MM Corto, 9MM Scurt

not to be confused with 9x18 Makarov

or 9MM Luger or 9MM Para Bellum

Isnt the 380 also known as a 9x17 and 9mm browning?

I believe so.

9x17 = 380
9x18 = 9mm Makarav
9x19 = 9mm Luger/9mm Parabellum
9x21 = 9mm IMI
9x23 = 9mm Largo
9x25 = 9mm Super Auto G

And despite all of those being "9mm", there is not a single bullet that would be suitable for loading in all of the cartridges.
