I did try discussing this with my wife.Maybe u just implement the basic saf armskote rules. Keep ammo, mag and piece separate under lock. Quick access maybe out but at least kid safe. Don’t clean or practice in front of your kids.
I showed her pictures of the trigger locks. I told her that if I buy the gun I will give her the key. And that only she can release the key so the gun can be used as a safety. All on top of also putting the gun in a secure locked case with the key to that case in her possession too. She just doesnt want any guns at home.
