Leader Willem

The Zipper pistol has a chance to drop from Leader Willem inside The Excrucible at The Grindstone of the Worthy in Carcadia Burn.

He is first faced during the side mission, The Mole's Gambit but you have to complete the following side missions first before reaching this point:

  1. Enter the Electi Pt. 1
  2. Enter the Electi Pt. 2
  3. The Council Divided
  4. A Traitor Within

After beating him for the first time,Leader Willem can then be fought again by paying the Moxxi's Big Encore Machine near his boss arena.

Aside from farming Leader Willem, the Zipper also has a small chance of dropping from regular legendary loot sources like red chests, golden key chests, and other bosses. You can speed up your legendary farming by using a boss farm or endgame build for your Vault Hunter.
