in the forward longitudinal direction of arrow t the lateral displacement of the trigger bar 30 is corrected by both the lateral restoring force imparted by biasing member 600 and the lateral force due to the effects of the trigger return spring that is in some embodiments the trigger bar 30 receives a lateral restoring force from two independent sources the trigger return spring and the biasing member 600 the addition of the lateral force contributed by biasing member 600 enhances the mechanical impact between the trigger bar 30 and the sear 50 as the trigger bar 30 and the sear 50 reconnect this added force in turn enhances the impact resonance at the trigger reset event allowing an operator to more easily ascertain when the reset even has occurred furthermore the longitudinal movements of the trigger bar 30 are not significantly impeded by the mechanical cooperation with the notch 660 of the biasing member 600 because the trigger bar 30 is allowed to slide freely in the forward and rearward longitudinal directions within the notch 660 the mechanical cooperation of the trigger bar 30 and the biasing member 600 does not impact the trigger pull weight additionally a secondary impact resonance is created between the first end 630 of the biasing member 600 and the interior surface.
