No, Look It Up!! :D ^^
Bullet diameter of a 9mm is .355; for a 38 it is .357. 38 case is longer. Additionally, a 9mm is designed to be used in a semi-automatic pistol, and a .38 is designed to be used in a revolver, although, there are a couple of revolvers that will chamber 9mm.
No, it cannot.
Pretty close to the same in ballistics. The 9mm is used much more commonly.
no, although the diameter of the bullet is about the same .356 for 9mm and 357/358 for the 38 cal. that metal cases will not interchange with other guns. i.e., the 9mm case does not feed in a 38 nor will a 38 feed in a 9mm..................
9mm 100-300 or so 38 Super 100-500 or so
.38 Special- 9mm is more powerful. ,357 Magnum- 9mm is less powerful.
9mm IS the caliber. If you mean what is it equivalent to, it is approximately the same as a .38.
No
9mm 100-300 or so 38 Super 100-500 or so
There are SEVERAL 9mm cartridges- the most common is probably the 9mm Parabellum (9mm Luger). A 9mm Parabellum BULLET (not cartridge) is typically slightly smaller than a .38 Special bullet- .356 instead of .357. The 9mm is frequently (not always) lighter- and shorter. Other 9mm cartridges (such as the 9mm Makarov) will have different bullets.
Close, but no. A .38 Special fires a .357 inch diameter bullet, 9mm Parabellum fires a slightly smaller bullet, but with more force. The .38 is a rimmed revolver cartridge, and the 9mm is a rimless automatic pistol cartridge.
9mm Parabellum cartridges (9mm Luger) HAVE small pistol primers. For some applications such as submachine guns with a free floating firing pin, a harder primer may be used. However, in most applications, the same primer used in .38 Special would also be used in a 9mm.
