Scoping in first person with the red dot is not aligned. To fix this go to mods\update\update.rpf\common\data\ai
and edit weapons.meta. Search for WEAPON_COMBATPISTOL then scroll down till you find
<FirstPersonScopeOffset>.

Replace these 2 lines with these:
<FirstPersonScopeOffset x="-0.00200" y="0.0000" z="-0.0100" />
...
<FirstPersonScopeRotationOffset x="1.00000" y="0.0000" z="0.0000" />
