Everytime I grab upgraded gear from the vault into inventory with the upgrade symbols showing, I have to open details on each and close before I can proceed. If I switch weapons in a hurry, I have to go back ASAP to make sure they are all fully loaded. Sometimes too soon to make sense for one round in a high capacity primary or heavy. Really, Thunderlord is fine with 54 rounds; but it can hold 60 with Field Scout!
