Firearms safety is a critical issue.  All responsible gun owners need to practice safe handling and operation of firearms.

Treat all firearms as if they are loaded. Never point the weapon at anything you are not willing to destroy. Keep your finger off the trigger until the target is in the sight. Identifiy your target clearly and have complete awareness of what is beyond it.

Firearms safety is the responsibility of every user of firearms. If you can’t follow them, all the time, then don’t carry one. This is a reminder of what happens when you disregard them!
