I have a HSc that is in an older box with the serial number shown as 7362 and I was wondering when this gun was made. The box shows a Kal. of 7,65 but the barrel in the gun is a 9mm kurz, the operators manual is written in German and the parts brake down page in the book shows all parts the same but it shows 2 barrels, one a .32(7.65) and the other a .380(9mm kurz). Could the barrel have been changed by the past owner and would the rest of the gun been left without any changes because all is the same except the barrels. The magazines seem to work fine and I have loaded .32's and .380's in the magazine and they both seem to fit fine. Is this gun safe to shoot .380's if the original gun was manufactured to shoot .32's? The serial number on the box is the same number as the number on the gun.
