Lucky here in OR we have very few restrictions on where you can carry and my work doesn't have a weapons policy so I carry all the time; however, I have a question for you. Do you ever go to restricted location during the day. Say you are out at work and you need to run by the Post Office or that you have to go in for jury duty. Do you leave the gun at home all day?
At least the OP is asking the questions and is willing to listen to advice. I have a safe that is secured to my vehicle with a heavy cable for when I have to leave my gun in the truck for legal reasons. I do admit that if there is a determined thief that the safe will like be taken though. Does that make me irresponsible? To me it just means that I have done all that I can do to mitigate the potential of my gun being stolen. And since we are blaming everyone but the thief here, why don't we just blame the governments and companies that but in place rules that force us to remove the gun from our person?
Answer; I use a very heavy aircraft cable attached to a welded rear seat bracket, attached in such a way as to be hidden and unable to be defeated without tearing the rear seats out (4door PU). This rig is completed by a large Kryptonite armored lock. It is all I can do to reach back to lock the trigger guard to the cable and I have long arms and small hands. In addition I have an excellent alarm system. The OP did not ask about tech advice, he asked about legality, which I admit did hack me off some. Read my original post, "if you can't secure it leave it at home!" YOU secure yours, I secure mine, so where's your problem? Read every word that I wrote. Where did I ever say don't blame the criminals? Hammurabi's code works for me! Done!
