The game tells you that you do more damage to Handymen when you shoot them in the heart, there's even a trophy for killing a Handyman by only shooting him in the heart.
Completed the game, thought it was fantastic although I'm confused by some parts of the ending. Potentially another thread for that? Just so there isn't a need for that spoiler tag pish.
