Okay I've been messing around with the item_3d.xtbl file to see if I can replace the default model of the weapon into its variants so that whenever NPCs use that same weapon they will have that model instead of the original one. (Ex: Replacing the SWAT SMG with the Gangland Tommy Gun so that whenever any NPC with the SWAT SMG show up, they will use the Gangland instead of that). So far I don't have any luck with it. I need some serious professional help with this kind of thing. Thanks for any feedback.
