A crossbow trigger and bowstring release mechanism with improved bowstring retention and release characteristics. The device enhances accurate and safe shooting with the crossbow. The trigger mechanism comprises a spring operated pivotal cam string release mechanism for releasably holding a bowstring in a drawn position. The string release latch is pivotable about a pivot point and has associated therewith a first sear surface. The trigger mechanism further includes a pivotal rocker latch member having a second sear surface which engages the cam pivot mechanism. The sear has an extended arm that engages a safety hammer release. Finally there is an improved dry-fire prevention pivot mechanism that engages an arrow when loaded to launch. When no arrow is present the dry-fire rocker engages the cam mechanism and prevents the movement of the cam to release the bowstring. |
