Plutonium

I would like to know if there is any tutorial on how to get the right weapon models and how to custom them for BO2 (T6 Zombies). I know how to custom them but i don't know if I have the right files

Does anyone know where i can find the mp5 and M1911 textures/models (Png files)
Thank you

GhostRider0125 i have copied it and i cant put it in greyhound do i need to load up something else first?

I have been looking for a tutorial and cant find any that shows how

GhostRider0125 it works also if its not for Multiplayer?

GhostRider0125 it doesnt work for me i must be doing something wrong
When i load (zone/all/zm.ipak) and i paste the M1911 name in the serach bar nothing comes up
