If you mean 9mm Parabellum (also called 9mm Luger)- no. the 9x18 (Makarov) is fatter and shorter than 9mm Parabellum. It is not a true 9 mm.

It depends on the bullet weights. The 9 mm (AKA 9x19 mm, 9 mm Luger, or 9 mm Parabellum) is faster than the .380 ACP (AKA 9 mm Kurz) except when you compare the lightest .380 bullets to the heaviest 9 mm bullets. If you compare the same bullet weights in each, the 9 mm is always faster.

No, 9 mm and .380 ACP (Automatic Colt Pistol) are not the same, although they are similar in some respects. The .380 ACP has a bullet diameter of approximately 9 mm, but its case length and overall design differ from the 9 mm Parabellum (9x19 mm), which is more powerful and commonly used in various firearms. Therefore, they are not interchangeable and should not be confused with each other.
Yes. .38 special is a revolver cartridge and .380 is an auto cartridge. Also, the .38 will almost always have a heavier bullet and more muzzle energy than a .380. The .38 bullet is 0.357 inches in diameter while the .380 is 0.355 inches in diameter. Technically, the .380 cartridge is considered part of the 9 mm class of bullets. [9 mm x 19 mm = 9 mm Luger or 9 mm Parabellum, 9 mm x 18 mm = 9 mm Tokarov, and 9 mm x 17 mm = .380 ACP]
The diameter of the the two bullets are just about the same, but the length of the brass case which holds the bullets are slightly different. The Makarov's case is 18mm long, while the Luger's (Parabellum) case is 19mm long.
Both Glock 17 9 mm and beretta 92 fs witch are butter because of their high durability.
The 9 mm Largo is a semi-automatic pistol cartridge that originated in Spain and is also known as the 9 mm Bergmann-Bayard. It was developed in the early 20th century and is characterized by its slightly longer case compared to more common 9 mm cartridges, such as the 9 mm Parabellum. The 9 mm Largo was used in various military and police firearms, particularly in Spain, and has largely fallen out of widespread use in favor of more modern calibers. However, it is still encountered in some vintage firearms and among collectors.
