The present disclosure provides a trigger assembly and related method for a firearm (e.g., an AR, SR-25, or M4 style rifle, or another type of firearm). The trigger assembly minimizes inadvertent discharge of the firearm by blocking the trigger from rearward pivoting until pressure is applied to the center portion of the trigger. The system and method employ a configuration wherein a camming surface is engaged with a machine portion of the lower receiver once the trigger assembly is connected to the lower receiver via pivot that extend through the trigger assembly and at least a portion of the lower receiver.
