Regarding the original topic, I think that if you felt comfortable, then that was what is best for you.
Like LT said, most people don't even notice, especiallly if it's a kel-tec. Prior to my CHL, I would have never noticed. Even now, someone would have to open carry or make it obvious.
Personally, I wouldn't. I'm not a large person, and I can't fight. I like being my own Trojan Horse. I don't want them to have any idea of my status if they have an attack on their minds.
Having said that, most friends and acquaintances know I carry. I wish fewer people knew, but I can't unring that bell.
