OK, now I'd go with 1.Allow me to rephrase:
1. Gun safety is important, and some safety rules need to be followed.
2. Gun safety is important for morons, but because of your high experience level and mastery, you are inherently safe. You don't need rules. Even if you keep your finger on the trigger and sweep everybody at the range, it's OK, because it's you.
3. Yo, blood, I'm a badass MF now!
What you added to 2 makes a world of difference. It now represents a cocky know it all who doesn't apply any safety rules.
