I've posted this picture because a lot of members have asked about the differences between Bersa Thunder Ultra Compacts and the Firestorm Mini guns. Note the conventional rounded trigger guard, the Firestorm brand on the gripstock and the fingergrooves in the front strap. The Bersa Thunder 45 Ultra Compact has the recurved "combat" trigger guard and straight front strap, with the Bersa logo placed low on the gripstock parallel to the front strap. Internal parts are supposed to be interchangeable, because they're virtually the same gun and they're manufactured in the same factory by Bersa S.A. in Argentina.
The Thunder 9 UC also has the grooved front strap.
