On the topic of Borg shields and guns, if the Borg came across a species that used projectile weapons in their rampage across the galaxy before TNG, they'd eventually adapt, since Picard took out two drones with a tommy gun, the Borg hadn't run into anything like it before, either that or Picard got real lucky!
You could always get the Borg with the first couple of volleys of anything. Then they'd adapt. Though they had seen energy weapons before, the Borg were always vulnerable to the first few rounds.
