Pangolin

Pangolin are one of the few manufacturers on Pandora that do not produce guns. They do, however, make Shields and Grenade Mods.

Trivia
The Pangolin ([see wikipedia]) is a primarily nocturnal, insect-eating mammal, which can curl into a ball for protection, and has a thick coat of scales to protect it. This same natural protection is no doubt what inspired the manufacturer's name.
