Default question on caliber?

im sitting here cleaning my uncles amt home defense pistol and the caliber reads .380 9mm kurz, now for the longest time i thought 9mm was .380 but i discovered i was quite wrong on that, bc 9mm = .357 so would amt read .380 9mm? and for that matter i accidently bought a box of 9mm luger ammunition the other day and is that differnt how from a regular 9mm? thanks

9mm does not = .357. .357 would be a 38 special or a 357 mag. 9mm = .355 or.356 depending on the bullet and it is the same diameter as a .380. A 380 is also known as a 9mm short or 9mm kurtz as you mentioned. The 9mm luger rounds you found are what is commonly known today as simply, 9mm.

You need to be careful in the 9mm world. There are 3 or 4 bullets that are the same diatmeter so they get a 9mm title but are different and all have to do with length.

.380(9mm short) is 9x17mm,9mm Makarov is 9x18mm,and 9mm Luger is 9x19mm.9x19mm Luger is what people think of as just "9mm".

You should also understand that a MARKING of 9mm does not mean that the BULLET is exactly 9mm. the "9mm" Makarov is actually larger in diameter than the 9mm Parabellum (proper name of the 9mm Luger). It is just a handy way of referring to a cartridge.

i did what skull crusher did and looked up 9mm in inches thats why i thought of it as the .357 bc its fairly close but i understand that 9mm is very different.... its why i stick with my .45 acp =)

In the 9mm class of cartridges;

9 X 17 = .380 = 9mm kurz = 9mm Corto = 9mm Browning
9 X 18 = 9mm Makarov (.365 bullet diameter)
9 X 18 Ultra (.356 bullet diameter) Older attempt at making the Walther PP more powerful
9 X 19 = 9mm Luger, 9mm Parabellum, Generic 9mm
9mm Federal = Rimmed 9mm luger for revolvers
9 X 21 Italian high performance round popular in IPSC competition
.356 TSW (Team Smith and Wesson) = 9 X 21.5
9 X 23 = High performance round introduced in Colt pistols
9 X 23 Largo Archaeic Spanish round
.38 Super Semi-rimmed cartridge introduced in the 20's in Colt pistols. Now popular in Mexico (where military calibers are outlawed) and IPSC competition.
.38 Super Comp Rimless version of .38 Super (more or less).
.38 TJ (Todd Jarrett) very similar to .38 Super Comp
.357 Sig Essentially a slightly lengthened and necked down .40 S$W
9 X 25 Dillon essentially a necked down 10mm

I'm sure there are others that are far more obscure.

ps: The shift key is your friend.

And the 9mm Browning Long, the 9mm Magnum, 9mm Steyr, and 9mm Glisenti. PS- I have ONE round of 9.8mm ACP, made 1910, discontinued at once. Think there were a few other obscure ones.
