Guys, My son is 12. He has been shooting a Mossberg Mini which he is beginning to outgrow. My buddy has a 7 year old and we have traded guns for the season as the Mossberg Mini works great for him. In return we were given an O/U Mossberg Silver which fits my son perfectly. The problem is every time he squeezes the trigger both barrels go off. To make sure it wasn't operator error myself and a buddy of mine have both shot it and had the same issues. I called Mossberg and their idea is to send it in. That would be rough as we are in mid season. Is there any trouble shooting ideas you all have for me to remedy this issue relatively fast? Thanks in advance for any help.
