Ok I can't pickup any better of a weapon for the auto weapon slot other than a bastard gun I see AK's and others laying around but they don't glow like all the others do any 1 kno how to fix this bug this is almost the 2nd time I had to play through the game with this piece of crap oh and when I go to shop's for the good guns they just say they are out of stock soo WTF

When you look at the weapon, does a circular arrow show up? If so, hold the use key "e" and it should swap the weapons.
