Smart Weapons
Smart weapons are guns that aim for V. Their rounds can lock on to a target and bend in flight, so a shot fired at an enemy behind cover can curve around it and still hit. Some fire small homing missiles instead of bullets, and the game describes one kind of Smart ammo as designed to fragment into shrapnel.
Smart Link
A Smart weapon only works at full strength with a Smart Link, an implant in V's hands. The game's tutorial says Smart weapons require a Smart Link to unlock the full potential of their targeting systems, and points V to a ripperdoc to install one. With the Smart Link equipped, Smart weapons fire homing rounds that bend their trajectory mid-flight.
Lore
A shard in the game tells the story of smart guns. Soldiers once needed weeks of combat training. Now smart guns lock on and fire homing rounds, as long as the shooter has the right implants. It was a pistol that started the smart revolution: the Yukimura, made by Arasaka. With it, even the worst shot hits the target, and it is still counted among the best handguns ever made.
