They have an alert about various trigger locks.
I have always believed that one should educate one's childern about firearms when the kids are realitively young or ask about tehm versus tell them no no no. When a child hears no, he/she wants whatever is not allowed even more. If educated about firearms, the mystery of them is mostly gone as well as the child has a good knowledge of safe handling and use. This helps prevent "accidents" and unfortunate injuries.
Also we must remember that trigger locks will mearly slow a person from unauthorized use.
