How to get sub weapon slot?

There is an explosive slot in there but in insurgency, the explosive slot can hold 2 different explosive type.
The GetPlayerWeaponSlot only able to grab the first explosive, unable to get the second one.
I use a for loop to print out all the slots, still no luck.

In-Game:

Console:

You see in the screenshot? It missing a grenade.
I'm wondering is there a sub slot function for it...
