A friend shot a dove yesterday with right barrel on his extractor 12 ga. He removed the empty and replaced it with a loaded round but could not close the gun as firing pin stuck out. After removing the barrels, he snapped the left trigger, so both pins now stick out. He tapped lightly on the pins, but they would not move back from the breech face. He did not try and cock the locks by turning the cocking rods for fear of damaging them. What could cause this problem and what should he do now?
