I would applaud your doing so and support your decision as your feeling uncomfortable in that situation would not be conducible to a nice meal, etc. However, the mere carrying of the weapon would not bother me, unless their demeanor was inappropriate. If some citizens in Kileen Texas has openly carried, perhaps some of the carnage could have been prevented. Passing laws to restrict the 2nd amendment rights of the citizenry does nothing to prevent criminals from breaking those laws -- HELLO -- they are criminals they don't mind breaking laws !!
By the way, I have a concealed carry permit but rarely actually carry the weapon. I got the permit so I could have the option to exercise the right granted by the founders before those who would limit these rights passed barriers to effectively remove those rights.
I conceal/carry, too, w/ permit. I rarely do it around town (maybe a mistake), except when hiking -- I like to hike up into the mountains behind town, and there are bears and mountain lions.
I carry a .40 S&W Sig P229 in shoulder and a BondArms .45/.410 snake gun in a pocket holster. I also have a .308 sniper rifle, as I like to shoot, strait, over long distances. It's an incredible feeling. It's just a hobby, but a potentially useful one.
Thanks for the conversation, BTW. You seem like a first-class FReeper.
