Why should you NEVER look down the muzzle of a firearm after a hang fire?

Because you won't be able to see down the barrel clearly

Because the misfired cartridge may slide backwards down the barrel and damage the firearm

Because the cartridge may still fire and cause serious injury or death

You can look down the muzzel so long as the safety mechanism is engaged

The correct answer is: Because the cartridge may still fire and cause serious injury or death. It is important to always treat a firearm as if it is loaded and never point it at anything you do not intend to shoot, even after a hang fire. Looking down the muzzle of a firearm is extremely dangerous and can result in serious injury or death if the firearm were to discharge unexpectedly.
