Does this bug happen in public version or in the paid version of the game? Did you test other sights equipped on a pistol, do they cause this bug, too?
It is in the paid version.
Yes just tested it on other weapons, and it did the same, and not only the Red dot but other sights aswell ! (Holo and Red dot, no matter what weapon is equipped)
I tried to set it up to one of the weapon i don't use, worked fine as long as i don't use it. The moment I equipped the weapon with a sight the game became buggy
