The current hand grenade implementation is a little too easy which brings gameplay issues.

Firstly the ability to throw a hand grenade is unrealistically fast. There is no readying of the weapon - the grenade is instantly available - and can be thrown with little disruption to firing down range.

Secondly, it is too easy to accidently throw a grenade. With the default binding of G it is possible to accidentally press this simultaneously while pressing F for fire mode.

Thirdly, the default key for inventories in previous games was G. I'm sure I'm not the only person to drop a grenade at my feet when intending to open a crate or dead body inventory.

I would like to suggest that the current key binding remain, but only to select thrown weapons. This should play the animation of retrieving the item, and possibly even readying it - drawing the safety pin - which does take time. Throwing the item could use the default firing action, or a second press of the grenade binding.

This suggestion would prevent the ability to seemingly throw with no disruption to firing, prevent unintended grenade use through accidental catching of the grenade key, or simply pressing the wrong key, and finally give attention to the player that this will be the next action.
