Abstract: An exceedingly simple, logical, and reliable trigger assembly that allows the trigger to release smoothly with very little applied force. The present invention provides an improved, exceedingly unencumbered trigger apparatus for guns utilizing the resistant force of a spring to drive a firing pin or piston. This novel trigger assembly employs a fluid movement of simply interrelated parts to fire a gun. The invention basically comprises a pivotally moving sear having multiple pivot pins, one of which is sequentially connected to multiple linkages also having multiple pivot pins. When the trigger assembly is in a state of engagement, the sear is perpendicular to the linkages. By actuation of the trigger, the horizontal alignment of the linkages relative to one another is slightly broken, resulting in the upset of the perpendicular alignment of the sear relative to the linkages through the multiple pivots.
