Claim:
1. An anti-dry fire system for a crossbow having a draw string for launching arrows, the anti-dry fire system comprising: a catch moveable between a closed position that retains the draw string in a drawn configuration and an open position that releases the draw string to a released configuration; a sear moveable between a de-cocked position and a cocked position coupled with the catch at an interface to retain the catch in the closed position such that after firing the crossbow the sear is retained in the de-cocked position by the catch; and a dry fire lockout moveable between a disengaged position and a lockout position that blocks the sear from moving to the de-cocked position, the dry fire lockout comprising a portion located behind the draw string, and a surface on the catch that engages the draw string, in the drawn configuration before an arrow is engaged with the draw string, such that when an arrow is engaged with the draw string the initial engagement with the portion occurs at a location behind the bow string to cause the dry fire lockout to move to the disengaged position.
