Does anyone have a problem when shooting their pump with turkey load and the action falls back when the shot is fired. I shoot a mossberg 500 and if I don't hold a tight grip on the forearm when I shoot the action falls back. I don't know if it is the recoil or what. If I hold a good grip on it it wont do it. It also doesn't do it if I shoot lite loads like bird shot. Thanks for any imput.[]
