Common sense is where many start to get lost and feel nervous....
ALWAYS Keep The Gun Pointed In A Safe Direction
This is the primary rule of gun safety. Common sense dictates the safest direction, depending on different circumstances.
ALWAYS Keep Your Finger Off The Trigger Until Ready To Shoot
When holding a gun, rest your finger alongside the frame and outside the trigger guard. Until you are actually ready to fire, do not touch the trigger.
ALWAYS Keep The Gun Unloaded Until Ready To Use
If you do not know how to open the action or inspect the chamber(s), leave the gun alone and get help from someone who does.
When using or storing a gun, always follow these additional NRA rules:
Know your target and what is beyond.
Know how to use the gun safely.
Be sure the gun is safe to operate.
Use only the correct ammunition for your gun.
Wear eye and ear protection as appropriate.
Never use alcohol, over-the-counter drugs or prescription drugs before or while shooting.
Store guns so they are not accessible to unauthorized persons.
