In my third legacy now. For the lift of my cannot understand why I cannot unlock this gun. I do not even use the M9, I just want it becasue it is the unly gun left for me to unlock in TDM mode. I have take treasure hunter to Gold in my first legacy.. nothing... I read using it does not help so I took it to silver in second and third still no show. Any advice on the last treasure piece? Then I can continue with my Hardcore modes weapons
Also, HC weapons unlocked? You don't call it Classic mode weapons? I fully respect you.
