Make grenades more interactive: add a pin that you have to pull instead of pressing trigger to turn it on. It just feels so much more enjoyable to pull and throw like in films instead of pressing trigger then throwing. And ideally you press grab to hold the grenade, the grenade handle is held by the pin, if you release the pin it would eject the handle unless you keep holding it with your index finger by pressing the trigger with it. If you then release the handle it will eject and start the fuze of the grenade. This way players have more control and can do funny things like kamikaze. And it feels more real, more immersive. It's the most realistic the grenade can get I believe, but this is not what I'm looking for, it's a VR unique and only way of interacting with grenades, it's fun and immersive. But if you really want to keep it as simple as possible then please consider having 2 options just like you were planning to do with auto and manual reloading
