My first Bersa was a nickel .380. Had several FTE during the first 200 rounds so I did not trust it for a carry gun. Also ammo was too high so I upgraded to the full size Thunder 9mm. Never had a hiccup in nearly a thousand rounds. It's a great gun. Added a 9mm uc in stainless. So far 600+ rounds and zero problems. IMO the 9mm Bersas are far superior to the .380 and are much more economical to shoot. Normal wear marks where slide meets frame; not a problem.
