Please note: you need to download GTA V Weapon Data which made by fkngoob due to ancient data corrupt my gameplay
Also after replace weapon.dat, you need to replace default.ide to avoid game crash due to game cannot understand what animation supposed to that weapon.

Copy and paste this lines in weapon.dat made by fkngoob:

I recommend use God Mode mods for CLEO from gtagarage to avoid dead and don't use for mission, use for kill aggressive drivers.
