TTT Weapon Models/Sounds/Materials

How could I take the existing weapons in TTT such as the Deagle or M4 and change their Models/Sounds/etc just for the server? For example I would like to download skins and use them in my server and force everyone else to use those same ones, just for my server of course. I’m not quite sure how to go about this without making the Models/Materials files overwrite the already existing, vanilla, files. If you don’t quite understand, please let me know.

Would I go about this by simply copying the existing weapons, renaming them something else, and just apply the different materials and models for them?

Anyone know? I’m just looking to basically replace the materials/models/sounds of the weapons on my server. The default, vanilla, weapons.
