It's actually not easy to shoot down a drone with a gun if it takes any measure to evade interception. It's not like shooting ducks taking off from a lake.
That said, last week the French navy did shoot at drones around the Île Longue nuclear submarine base, but as far as I understand just one drone came within close enough range to be targeted by radio jammers (which means maybe a few hundred meters at sea) and either it went away on its own or sunk but it apparently wasn't retrieved. It's very unlikely they could shoot it down with conventional firearms.
