Depends on what you want both will do fine for personal protection or target shooting. The 9 is a slightly smaller lighter round and ammo will cost you less. The 38 supper has more punch behind it and really is on par with a 357 sig or a 40 cal. Also the 38 will tend to be a bigger gun so if you looking to carry keep that in mind too.
Whichever one suits you better.
The main difference between a 9mm round and a .38 round is their diameter. A 9mm round has a bullet diameter of 9mm while a .38 round has a bullet diameter of .357 inches. Additionally, the 9mm round typically has higher velocity and energy compared to the .38 round.
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

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.
No, it cannot.
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.
No, Look It Up!! :D ^^
