Common sense serves here. In my home, my private office, or at a rural property under my control the firearms may be brought out, made safe, and discussed. The handgun I conceal as I go about my day outside my premises will remain concealed. They aren't to be regarded as objects to mull over. It doesn't matter whether it is at a local restaurant, gun shop, or curb side in the front seat of a vehicle.
I recently was involved in a concealed carry discussion over breakfast with some friends at a local restaurant, one of whom purchased a new Beretta 92 and was fretting about concealing it. I refrained from even positively answering whether I was carrying at that moment when I was asked to show them what I was carrying. In our small Texas town, it really wouldn't have been a big deal to unload a pistol and put it on the table for all to discuss it as nearly everyone around here has a gun of some sort on them or near by. They couldn't detect it and they didn't have any "need to know."
If I'm at the house of a few trusted gun buds and they wish to inspect a model of handgun I am carrying then I may allow it in private, at my discretion.
Remember, no one has to know.
