Sig

Sig was a form of notoriously inaccurate blaster gas that produced armor-piercing shots. Pressurized sig was also often used in plasma grenades. Due to its armor puncturing abilities, sig was almost banned and became favored by criminals several centuries before the outbreak of the Clone Wars between the Galactic Republic and Confederacy of Independent Systems. As a result, the Bureau of Sig, Spice and Slavery was formed by the Republic in order to combat organized crime.
