The 9 mm driver unit in in-ear headphones is the size of the speakers. It means that each earbud has a 9 mm speaker.
No. There are more than a dozen DIFFERENT "9mm" cartridges, and they do not interchange. The most common is 9mm Parabellum- also known as 9mm Luger or 9x19. It does NOT interchange with 9mm Kurz, 9mm Corto, 9mm Makarov, 9mm Ultra, etc.
No. There are several different calibers that are called 9mm. These calibers are not interchangeable. A quick rundown of 9mm pistol cartridges: 9x17 also called 9mm Kurz, 9mm Short or .380 Auto 9x18 Makarov, also called 9mm Makarov 9x19 also called 9mm Luger, 9mm, 9mm Para, 9mm Parabellum 9x21 also called 9mm IMI 9x23 also called 9mm Long, 9mm Largo
9mm MKV is not the same as 9mm Luger.
The .380 IS a 9mm- a 9mm Short (also called 9mm Kurz or Corto). There are more than a dozen different 9mm cartridges. Most people mean the 9mm Parabellum (also called 9mm Luger) when they say 9mm. The 9mm Parabellum IS a longer cartridge than the .380 .
9mm Largo and 9mm Parabellum are different guns. No.
Good answer below. The "9mm Luger" is properly the 9mm Parabellum, but it is also called the Luger. There are about a dozen different cartridges with 9mm in their name, but the 9mm Luger is the best known.
probably If the pistol is designed for 9mm Luger, 9mm Para, or 9x19, yes.
No such ammuntion as 9mm rugger
The common 9mm cartridge is known by many names. All of the following 9mm's are one and the same: 9x19mm, 9mm Nato, 9mm Luger, 9mm Parabellum. There are no 9mm cartridges specific to Glock or Smith & Wesson.
Yes. 9mm Luger is the 9x19 cartridge, also known as the 9mm Parabellum, and that's what the 9mm Sigma is chambered for.
Glock is a brand. 9mm is a caliber size. So, there is no difference between a 9mm glock and a 9mm of another brand as far as caliber size.
