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
No. .380 ACP is 9x17. The 9x18 is the Makarov- not only a longer cartridge case, but the bullet is larger (the term 9mm is used loosely) Unlike revolver cartridges that headspace off the rim, these headspace off the mouth of the cartridge case. Do not try it.
Yup.
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. 32 ACP vs. 380 ACP
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.
Many makers offer firearms that shoot the 380 ACP.
NEVER SHOOT AMMUNITION IN A WEAPON NOT CHAMBERED FOR IT!!!!! Do not attempt this.
Same thing. Yes.
Retail value, you'd be looking at the $200 - $400 range, dependent on condition and calibre (9x17/.380 ACP or 9x18 Makarov).
No-- If you will GOOGLE .380 ACP and also GOOGLE .32 ACP. You can see the difference in specifications. First item each page "WIKI"
