Stevens 511/Savage 311 double barrel
Problem. When front trigger is pulled safety button slides to rear to safety position and the second barrel will not fire-safety is on. Rear of front trigger rides up safety lever, moves bottom of lever to rear and pushes safety on. If hold thumb on safety button when firing, safety will not move to rear and second barrel will fire. Seems that the safety spring is weak, but if safety is moved from safe to fire and back manually pressure is required, does seem weak?. If safety spring is problem, how do you remove and replace? Any help appreciated.
