Option to disable weapon auto swap

I hate that the game auto swaps for me once i run out of ammo. 

I want to have an option to turn it off.

I AM A GOOD PLAYER AND IM AWARE OF WHEN MY ROUNDS ARE SPENT AND I NEED TO SWITCH. 

Sooo, you can see why it can be very annoying when im on a 1 v 3 and about to get a win ... but oh wait... the game auto switches as i press to switch guns (so the game swapped back to the gun whose clip was depleted)... sooo now im dancing in front of people switching guns and that split second window of opportunity i had to win with my upper hand was just stolen from me by a bad game mechanic.
