The Thunder 380 is a lightweight, relatively small semi-automatic pistol series chambered in the .380 ACP caliber made by Argentine firearms manufacturer Bersa, S.A.[1] It is similar in design to the Walther PPK.

The Thunder 380 is suited for concealed carry due to its small size and rounded trigger guard.

[3] The Thunder 380 is quite popular in many South American countries, where the .380 ACP is often the most powerful cartridge allowed for civilians.

The blowback, fixed-barrel design theoretically aids accuracy, and it appears that the vast majority of Thunder 380 users report favorably on that issue.

The frame features a long rearward tang over the grips, which effectively protects the shooter's thumb web from hammer-bite or slide-bite.
