HandGrenade
so, in the init field:
this addweapon "HandGrenade"
this addmagazine "HandGrenade"
on the other hand, you can do:
this removemagazines "HandGrenade"
this removeweapon* "HandGrenade"
* note: in my source, they speak only about
this RemoveAllWeapons; ... ; ...
maybe removeweapon wont work...
but the name for a handgrenade is,
HandGrenade
easy huh
