I guess not. It’s only a question of spawning the actor at the right transform and applying the right impulse…
I opted for the above solution because I don’t need the grenade to simulates physicx while flying, as soon as it hits something it simulates physics and the behavior is totally convincing for my standard 
I guess it’s also a lot more easy to tweak than a 0.5 or less Kg object simulating physics.
