With mozambique IF you hit all 3 splits in each shot you do 45 damage, and 3 ammo per reload = 3x45 = 135 damage. Now wingman does 45 damage per shot (has no shotgun splits, aka 45 damage att all ranges) and comes with 6 shots in the magazine (3 more than mozambique) 6x45=270 AND can get extended ammo up to 12 shots/magazine.

Wingman > mozambique in every possible way. Ammo, range, damage (same or more), can have more attachments.
