Actually your wrong you don't have to have an exotic equiped for you to not have any primary you just upgrade is with full legendarys on and still takes it away from your hands WHY? Because the games considers it as a new drop/ item so it puts it in inventory not hand trust me I'm not wrong you can test it out yourself
