Gub

root@bandit-db:~$ cat description.txt

A legendary Bandit pistol locked to corrosive damage, built around heavy per-shot damage and a large magazine. It is at its best against armored targets, where its corrosive damage and strong impact let it hit well above what most Bandit pistols can manage.

During the 2013 Loot Hunt, Sinkhole briefly had a guaranteed Gub drop on October 19, 2013. A hotfix released that day also increased both its damage and magazine size.
