3 months after 9/11, we went on our honeymoon through the international terminal at the airport. They x-rayed my carry on bag, and x-rayed it again, and let me go. The same bag was hand inspected in Jamaica, very thoroughly I might add.
Mid week at a Sandals resort I was looking for something in my bag, and found a full clip of .40 cal hollow points. Needless to say, I disposed of the ammo, and stored the clip in my checked luggage. I might still be in jail if it were found.
NEVER USE A RANGE BAG FOR A CARRY ON. EVER.
Just my 2 cents.
