Is all 9mm Ammo the same?


May 17, 2009, 04:32 PM
I know nothing about 9mm's and am thinking of getting one. My pistols are wheelguns.

Will any 9mm shoot any 9mm bullet? I guess the reason I'm asking is what does it mean when the box of ammo says 9x18 or 9x12 or whatever?

no , all 9mm is not the same. You should get better answers here soon, but the most common 9mm is 9X19, otherwise known as 9mm Luger , which are the same or interchangeable. THere are lots of different 9mm, 9x18 (soviet), 9x23 (competition mostly) 9mm kurtz a.k.a. .380. These are NOT interchangeable, but most common 9mm is 9mm luger/9x19. Refers to diameter and length of bullet.

not at all... 9x18 is a soviet round that is shorter than a 9mm luger and actually larger in diameter... if you get a 9mm be sure you know which you are getting. they will not function in guns interchangeably... so... essentially.. just be sure of what you are getting.. I have seen more than one person mess up their gun by feeding it the wrong ammuntion...

rcmodel pretty much summed it up, but just to clarify, the 9mm Parabellum, 9mm Luger, and 9x19 NATO are all different names for the same cartridge. When people refer to "9mm", this is the cartridge they mean. All those others that he listed are different cartridges and are not interchangeable.

And guess what?

None of them are actually 9mm!

But they're close. Typical jacketed bullets are 0.355 inches and lead bullets are 0.356 inches, where 9 millimeters is actually 0.354330 inches. I guess they figured it was close enough, considering that they already had 38 caliber set at .357 inches.

if you are a wheelgun guy you should appreciate the differences between .38 special and .357 magnum. in some guns you can shoot both, in others no.

"...None of them are actually 9mm!..." A .38 Special isn't .38" either. Nor does .308" convert to 7.62mm.
" some guns you can shoot both..." You can shoot any .38 Special ammo out of any .357 Mag, but not the reverse.
You won't be finding any firearm chambered in 9mm AE. It's a .41 AE necked down to 9mm. Neither cartridge is loaded by anybody.
