No, seriously, stop touching it.
We all complain about venues, be they local gun show or a national convention, that are posted NO CONCEALED WEAPONS, which therefore demand mandatory coonfingering outside the door in the name of safety.
The flip side of that is that if they let you carry your loaded gun inside, you need to be a big boy or girl with it, and that means not whipping your loaded heater out in a crowded room to check and see if your gat fits in that $8.99 nylon sausage sack real good. Leave your piece in the holster and ask to borrow a demo gun, for Browning's sake.
If you don't trust yourself to be able to keep from pulling your loaded gun out, or think you are a special snowflake who is SO SAFE that you would NEVER screw up, please consider not carrying to the NRA Annual Meeting, okay? Yes, CCW will be allowed in that venue here in Indy this April, but that is not your ordinary gun show. A ****-up in there really would be "the shot heard 'round the world."
Make Bloomberg pay for his propaganda, okay? He can afford it. Don't give it to him for free.
