9 millimeter is the caliber. IMPROVING ANSWER: A "9mm" bullet is actually .355 or .356 of an inch in diameter. So the caliber is about .36, but nobody calls it that because it would be confusing. Everybody calls it a 9mm and if somebody asks you what "caliber" that pistol is, you can answer "It's a 9mm" without having to add or explain anything. further improve: 9mm is the correct answer. you can find the caliber by measuring the diameter of the bullet. translate to millimeters or inches and that's the caliber. 9mm is a 9mm caliber not "around .36"

No, the calibers and chamberings are completely different. It is not safe to attempt to fire any caliber of ammunition in a gun, other than what is stated on the barrel. actually the 380 caliber is almost equal to the 9mm. the 380 caliber is often refered to as a 9mm short. the difference is the 9mm case is slightly bigger then the 380 case and the 380 bullet might be a little lighter.......................
