99% Story Overall Completion

I earned the Platinum or all the Achievements and got the Cannon from U-Play using Points.

I want 100% for the main Story, but stuck at 99% overall completion, got 42 of the 43 Unlocked Weapons. What is this weapon and how do unlock it?

It's probably a unique weapon.
