To the gun itself that is... I keep a Bersa 380 in a compartment inside my truck at all times - my "car gun". Keep it there so that if I need to CCW (I am licensed) I have a gun and holster at the ready. My truck stays parked in my work lot all day (secure lot) but the temps inside during these hot summer months must reach 100+ degrees inside. When I check the pistol at the end of the day the gun is pretty darn hot- so is the spare mag w/ammo.
Does this pose any danger or harm the gun/ammo at all? The ammo isn't going to cook off in my car is it?
