They will react differently if the weapon was suppresed or not, there are, by default, some checks to know if a weapon is suppresed or not but you can manually add more.



There is a default list of weapons, to add a weapon to it just paste this in console
like by example:
they will investigate passively if the gunshot was from a surpressed weapon,
to remove a weapon
just type in console
like by example
and to see what weapons are in the list just type this in console This would print a list of weapons in the console so you can see if your weapon is there or not (keep in mind if a weapon has a suppressor then it should work without this, this is just in case it doesn't work)
