The subject of the invention is an improved trigger and trigger mechanism that compensates for an undesirable movement of the firearm from the aimed direction, when the shooter presses the trigger. The trigger (1) consists of the fixed part (11) of the trigger (1) and the pivotal part (12) of the trigger (1), whereby the fixed part (11) of the trigger (1) is lever mounted to the remaining trigger mechanism (2) or linearly mounted to it. The pivotal part (12) of the trigger (1) is pivotally mounted to the fixed part (11) of the trigger (1) through an axis (13). The axis (13) of the pivotally mounting, around which the pivotal part swings, (12) lies in a plane (P) that is defined by the longitudinal axis (A) of the trajectory of the projectile in the firearm and longitudinal axis of the handle (3) of the firearm, whereby the axis (13) of the pivotally mounting is essentially parallel to the longitudinal axis (A) of the trajectory of the projectile in the firearm or, vis-a-vis the longitudinal axis (A), is at an angle less than 80 degrees in one or the other direction. The pivotal part (12) of the trigger (1) in its neutral position, when no force of the shooter's finger is applied, essentially extends in the plane (P), but when the pressure of the shooter's finger is applied to it, it moves from its neutral position around the axis (13) of the pivotally mounting outside the plane (P) by the angle of divergence (a). The trigger (1) also optionally includes a spring element (4, 5) that holds the pivotal part (12) in the neutral position when no force of the shooter's finger is applied, irrespective of the position of the firearm, and returns the pivotal part (12) of the trigger (1) to its neutral position when the pressure of the finger on the pivotal part (12) subsides. The trigger (1) also optionally includes limiting means (6) that prevent deviation of the pivotal part (12) of the trigger (1) over the maximum possible angle of divergence (a) of the pivotal part (12) of the trigger (1).
