I am of a different mindset on gun security than some on here. I do believe in keeping your guns locked up and as inaccessible as possible but I do not believe all this cloak and dagger "hide them from the light of day or the bad guys will get them" stuff. It is just to fatalistic and conspiracy minded for my tastes. If you are going to enjoy collecting I think it is only natural to use, show to friends, discuss, etc. If not then why are you collecting? If it is purely self defense and you feel you are in that much danger then build a bunker and hide your armory there. In fact why not live in it...that would be safer than a house. It is true that someone with a masonry blade and some time can get into most anything but what do you think the odds of that happening really are??? We might as well be worried about being hit by meteorites. Most intruders are going to grab what they can easily and quickly carry away. Not stand around using loud power tools that they hauled in through the window or found in your garage. If you are really worried get a dog. My partner used to work for Protection One home security and the studies show that the NUMBER ONE defense against theft is a dog, second is a well lighted perimeter.
