Does anyone here leave pistols locked inside their vehicle for any amount of time? I worry about what the Arizona heat would do to ammo if it's left in a vehicle. I wouldn't leave a pistol in there all day, but if I were to make a stop somewhere that did not allow concealed carry, I would just lock it up in a car safe in my vehicle. Has anyone heard of any reports of casings exploding from the heat? I've been here for less than a year. Coming from Alaska, I never worried about these things. Wanna kill these ads? We can help!
