Should I give the flintlock pistol to Ruben or Q?

Q freezes and does not use the gun

Ruben missed the shot but Carla came to the rescue.

If you give it to JAX then you sneak and follow margot to catch her but jax ruins the plan, he talks loudly so margot can hear ir then he shots to her glass of wine and then she stands up and shot ruben but carla use electrical shock she fall down on the ground and then ruben misses the shot. Safe everyoneeeeee is safeeee.
