My wife and I have 4 kids, aged 11, 9, 7 and 3. We have four firearms in the house. My wife has her Walther PK380 for her concealed carry and it sits in her purse, locked and loaded and safety on. There is a Smith Sigma in .40 loaded, empty chamber. My concealed carry XD40 sc is locked and loaded and ready to go when I am carrying, otherwise it is loaded with empty chamber. Lastly, there is a Mossberg 500 20 gauge loaded with an empty chamber.
We have been very diligent about teaching our children about guns and gun safety. My oldest is just starting to get curious, so I see a trip to the range with my wife's gun, or maybe renting a .22 pistol for her.
