F3 Unique weapon mods/attachmaents

[slider444]

i like adding attachments to weapons and alot of F3s weapons can be modded but not the unique ones. is there a mod or update that will allow this?
would really like to be able to add a silencer to Col Autums 10mm pistol for example.

Not unless you make a mod that does it yourself.
