ABSTRACT:
An adapter for a single-stage trigger weapon which converts the trigger system from a single-stage trigger with a constant trigger pull force to a two-stage trigger pull system, wherein the required second-stage pull force is perceptibly greater than the required first-stage pull force. The increase in the trigger pull force occurs immediately prior to hammer release and provides the shooter with an indication of imminent weapon discharge. The adapter pivots about a fulcrum between the first and second stages.
