This bullet was designed for early blowback pistols which lacked barrel locking mechanism. The locking mechanism is unnecessary for .380 ACP since it has relatively low bolt thrust. The recoil spring and slide are enough to buffer the recoil energy of the round.
Since this makes the production of the gun using this bullet simpler, there by reducing the production cost making the gun cheaper. It also allows the barrel to be permanently fixed with the frame, this promotes the accuracy significantly.
Alot of modern weapons are chambered for this bullet including machine-pistols and sub machine guns.
Bullet dimensions
This bullet has seen many wars as its most popular uses were by German officers in WW2 in Walther PPK and by Italian in Beretta M1934.
How ever its not very suitable for active combat because it doesn't provide suitable penetration for combat. But because of its small size and low recoil its quite popular in civilian market for self defence, and is a viable choice for concealed carry pistols.
