Take it from someone who as a kid shot a gun off in the house by mistake if you have kids and guns the guns MUST BE LOCKED UP! Kids love to explore and show off and that can be deadly. Luckily as a child when I shot the gun in the house nothing happened but it could have been worse. As for exposing them to guns I have a 5 and seven year old and I have started them off with BB guns (only with my direct supervision). This is a fun easy way to expose them. Ii would not leave a loaded gun in the house of car unless it was locked as your kid will find a way to get to it. Personally I bought a biometric safe and Ii keep it next to the bed for home protection. There is no way the kids can get into it and it opens fast for me if I need it.l
