Loughner declined from the army, but passed a background check to buy a gun?

[guineapig]

To the people that own and carry guns around all over the place for protection.

If somebody pulled a gun on you (you do not yet know the reason why), Do you grab for your gun right away and hope that you can:

1. unholster it,
2. cock it and
3. shoot it

before they have time to pull the trigger?

If not, you gun isn't really protecting you. Now the gun in the house argument has a little more weight as... if you are a light sleeper, you might wake up to a home intrusion in time to arm yourself. If your both carrying though chances are you will both get shot.
