NO. The .380 ACP is a 9 x 17 cartridge. The 9x18, also known as the 9mm Makarov, is not truly a 9mm cartridge- it is 9.27mm. The cartridge is too long, too fat, and too powerful to be shot in a .380 ACP pistol.
The case of the 9x18 cartrdige is 1mm longer and the slug is slightly wider. In metric .380 ACP is 9x17.
yes i did it to mine
It shouldn't chamber, but, if it does: NO!!! DANGEROUS!!! UNSAFE!!!
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.
NO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! DO NOT ATTEMPT TO DO THIS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Never fire ammunition in a weapon not specifically chambered for it. DANGER, DANGER, DANGER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
9x18 is the Makarov cartridge. Browning never made a firearm chambered for it. They did, however, make such a pistol in 9x17 - otherwise known as the .380 Automatic Colt Pistol. It was actually the Beretta 84 'Cheetah', badge engineered and marketed as the Browning BDA 380.
Yup.
Depends. .380 ACP is used to refer to the 9x17 cartridge. It is not interchangeable for use in 9x18 (9mm Makarov), 9x19 (9mm Parabellum/Luger), or any other firearm designed for any cartridge other than the .380 ACP/9x17 cartridge.
No. Not all 9mm cartridges are the same. 9x19 (a.k.a., 9mm Luger, 9mm Parabellum), for example, is different, hence, not compatible with other 9mm cartridges, such as the 9x17 (a.k.a., .380 ACP), 9x18 Makarov, 9x21, 9x23 Mauser, etc.
No. Shoot only the caliber printed on the barrel.
