The rounds can both be used in revolvers and autoloaders, but are not interchangeable with one another .


Although some extraneous patrol use the .380 as a basal weapon, American patrol and military forces see it as a backup weapon, as it lacks the power of similar-sized pistols like the 9mm and .38 Special. Its primary coil function remains that of self defense for civilians, as its modest size allows for easy concealment and it can hold a relatively high amount of rounds.

Power and Performance

The office of .380 ACP gun is perceptibly below that of 9mm weapons. The maximal speed ( 1000 FPS ) and energy ratings ( 148 MPa ) of the .380 are about 40 % below a 9mm, both using JHP+P type loads. While this means the .380 is less destructive, it besides performs with less of a recoil, making it a more accurate weapon in short-range, rapid-fire consumption. The 9mm has a utmost speed of 1,400 FPS and an energy rating of 2465 foot pounds, and is by all measures a more brawny cartridge.
