Have a kid on the trap team that has a Mossberg 500 with broken tabs on his trigger group. It allows the front of the trigger group to droop down and the action comes out of battery without firing or pressing the release. Has anyone successfully repaired this problem with epoxy or JB Weld and had it last or would it be better just to replace the trigger group? I was thinking it might be possible to build up the broken area and reshape it but not sure it would last long.
