Typically, they're about even.. the bullet diameter .38 Special is larger by a negligible amount - .357, as opposed to .356 of the 9mm Parabellum.
.38 Special- 9mm is more powerful. ,357 Magnum- 9mm is less powerful.
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.
You have a Smith and Wesson model 14 38 special. The 38 refers to the diameter of the barrel. That barrel is 38/100 of an inch in diameter. A 45 automatic has a barrel that is 45/100 of an inch in diameter. A 9mm has a barrel with a 9mm diameter. You can shoot 9mm ammunition from a 38 special. A 22 pistol has a small diameter barrel.
Not muchThe diameter of a .38 special bullet is 0.358 inch, which is 9.09 mm. ALOT. the diameter isn't the only thing to consider. although the calibers are close the 9mm and 38 special are no where near each other. a 9mm is usually 9 x 19mm and is 115-124 grains and a 38 special is approx. 9.07 x 39mm near 160 grains and obviously packs more of a punch. fire a 9mm and then a 38 special and it will make sense.
Before this can be answered, you actually have to ask a question.
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.
It depends on what cartridges you are comparing. Some 9mm is. Also, 9mm is also availabe in Plus P.
The 380 ACP, also known as the 9mm Short, 9x17, 9mm Browning, 9mm Kurz and 9mm Corto uses a .355 diameter bullet. The 38 special uses a .357 diameter bullet. Additionally, the 380 ACP is designed for a semi-automatic and the .38 special is designed for a revolver.
No. Never attempt to fire ammo in a weapon not designed for it. Dangerous.
DO NOT ATTMEPT THIS!!!! There is a difference of .002 between the diameter of the projectiles.
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.
