Note that the gun you linked is 4-5 inches in total length. It's still quite small, but not similar enough in my opinion to a 2-inch prop gun.
EDIT: The gun is 3 5/8" in length.
At any rate, my problem is not the TSA agent's actions anyway, but her justification. If she had just shrugged and said "I know it's stupid but I have to confiscate this", then we wouldn't be talking about her. Instead, she heaped more coals on the already absurd security panic fire by suggesting that someone could be menacing with a 2-inch gun. This is the kind of crap that spawns memes.
