Yeah. Do I have permission to give it to other people??

it’s yours
Thank you so much 
Qustion is that only for the pistol mk2 or all mk2 weapons
Hello, not at all, simply edit and add the weapon hash 
So I have to add the other mk2 guns?
It depends on what you need… if you want to modify damage of the simple pistol you’ll have to add the “WEAPON_PISTOL” in the allWeapons list. Same for every weapons you want to modify the damage.
So for example {weaponHash = “WEAPON_PISTOL”, weaponModifier = 0.1},
Also whould it be on a new line
Yes and yes
