Coming weapon with nade launcher...idea

[Mael]

So its kinda 2 weapon in one..and it should work right ?

You'll need to modify the source. The change/reload weapon animation is not in the weapon models. It doesn't matter what the model is, when you change or reload the weapon is lowered then the weapon is switched and raised.

The closest thing you can get without modifying the source is to make two models, one rotated and one not. Changing between weapons will take place the same way but once the change is complete it will obviously appear tilted.
