Hey everybody. I'm new to this forum and relatively new to owning a firearm. I have had a Stevens savage model 320 for about 3 months now. I watched several videos on taking it apart and cleaning it and have cleaned after every use so far. However today after shooting some cans in the back yard I came into clean it but as I pulled the trigger out two additional parts fell out. A short spring and a flat metal peice about 8 inches long. Out of all the videos I watched nobody removed this peice and I can't figure out how to reattach it. I have seen it wgen i dissamembled everytime but not sure where the spring goes. Somebody please help.
