My friend just got a Bersa Thunder from his dad. He was wondering about ammo. He got some rounds with the gun. They say 9mm on them. Does he have the wrong ammo? Why would the ammo say 9mm if it is for the .380? Thanks for any help.;
Bersa calls both of their lines "Thunder". If the gun looks like a Walther PPK, it's probably a .380acp. If it looks like a Walther P-88 (full size), it's probably 9mm Parabellum. The full size models also come in .40. They also make "compact" versions of the "full" size in 9mm and .45 acp.

Here's a short history of the Bersa. http://world.guns.ru/handguns/hg159-e.htm
