My 19 y/o son has the combination to the gun safe for a SHTF scenario. I can not carry at work (nuclear power plant) so my EDC is obviously in the safe. The loaded 870 HD shotty is in the same safe also.
If a home-invasion were to go down, and my son had time to open the safe and pull a weapon, could I be in trouble for allowing someone under 21 to have access to a handgun? Or am I ok since it is inside my own home?
