I know it's a HUGE "NO-NO!!" I had someone admit to me he did accidentally as he was out running errands and such... He got to the counter to buy a book of stamps... Then it hit him as he went to get the money out of his pocket.... An LCP!!! He played it off and no one notices. Needless to say the SCARE of his life....I told him "U dodged a bullet today dude!!" I told him "LESSON LEARNED" stop, think, and read signs! In addition OBEY FEDERAL LAW!! I liken his experience to a kid cutting the tag off a pillow or mattress! Be careful & stay vigilant fellas!!
