Could someone tell me what mission you get the 4th weapon slot in? I thought it was from saving Roland but I did not get one. Thanks in advance.

I would also like to know how to get this. I have been searching, I checked quest guides, and nothing so far has given any indication how to unlock 4th weapon slot. Though others that I have ran into has all of their weapon slots.

HELP!!!
