There are 3 NRA fundamental rules. There are actually 10 total from the NRA, sometimes refered to as the 'Ten Commandments of Gun Safety'
The 3 NRA fundamentals are:
1. ALWAYS keep the gun pointed in a safe direction
2. ALWAYS keep your finger off the trigger until ready to shoot.
3. ALWAYS keep the gun unloaded until ready to use.
With a self-defense gun, it is always ready to use, so we keep them loaded, so number 3 is correct, but we should be ready to use it if needed.
The remaining rules from NRA are:
4. Know your target and what is beyond.
5. Know how to use the gun safely.
6. Be sure the gun is safe to operate.
7. Use only the correct ammunition for your gun.
8. Wear eye and ear protection as appropriate.
9. Never use alcohol or over-the-counter, prescription or other drugs before or while shooting.
10. Store guns so they are not accessible to unauthorized persons.
