Although the 9x19 and 9 Kurz (380 ACP) both use the same diameter bullet, the 9x19 is a tapered cartridge and thus, the 9 Kurz will not go far enough into the die to size the case. The 9x18 Mak definately can not use either the 9x19 or 380 die as the bullet diamter is so much greater. Not sure about the 9 Ultras (9x18 and 9x18.5) but they are cylindrical and should work in a 380 die.
