Remove Mozambique from the game untill you have buffed it to be a decent gun. It is a shotgun but it deals absolute garbage damage and it acts as a normal pistol but with 3 ammo..
Yup, the Wingman does the same damage as the Mozambique if you land all 3 parts of the shotgun hit. Plus the Wingman has more ammo and can be upgraded with an extended mag.
Mozambique shot should do at least 18 to 20 per pallet.
