what is 9x17 ammo
The 9x18 bullet is .008 larger than the 9x19. The 9x17 (.380 ACP) is a straight case that may insert part of the way into the chamber. If you misloaded the case would be jammed in and not fully chamber, so it would not fire. The 9x18 is enough larger it probably would not enter the chamber. know a 9x19 will not fit in a 9x17 mag, what would happen if a 9x17 was chambered and fired in a 9x19. My whole family has 9x19's in various frames, except my girl friend did not like it and went with a 9x17 and I am concerned with cross loading and having a 9x17 chambered into a 9x19.
The .380 ACP (Automatic Colt Pistol) pistol cartridge is a rimless, straight-walled pistol cartridge developed by firearms designer John Moses Browning. The cartridge headspaces on the mouth of the case.It was introduced in 1908 by Colt, and has been a popular self-defense cartridge ever since.he .380 ACP was designed to be truly rimless, and headspace on the case mouth instead of the rim for better accuracy. These designs were intended for blowback pistols which lacked a barrel locking mechanism.
