These are the two (2) answers to "Where should I keep guns when they are not in use?" I guess we could add "slung," as in "longarm."
The idea is to prevent access by the irresponsible, ill-intentioned and/or ignorant. I wish I could tell you that list was only criminals and children but it's not; a local retired police detective tells the story of playing card with some friends and having taken off his (personal) Browning Hi Power, holster and all, because it kept hitting the chair. As the afternoon wore on, he made a trip to washroom -- and forgot his gun. When he returned, the pother players had his gun out and were fiddling with it. "We saw it had gotten cocked," they told him, "and we were trying to fix that."
Yeah. No damage done -- that time. Sometimes the outcome is far worse: recently, an Indianapolis father was shot and killed when his child picked up a revolver he'd laid down. It wasn't secured. A safe, a locked case, a trigger lock, a locked room, even a high shelf -- hang it from the ceiling fan for all I care, as long as it is out of reach of anyone but you. When your gun leaves your immediate control, you need to secure it.
Safety is a habit that must be cultivated. Tamara's sidearm is either holstered and on her belt, or securely stored (for Roseholme Cottage values of "secure.") When not secured, mine is carried off-body due to my work (empty holsters are deemed inappropriate at my workplace) -- and Tam's caught me forgetting it in the washroom when I have been carrying it holstered. We haven't cultivated the same habit. In a child-free home where all visitors are vetted, it's not such a big deal -- until it is, during some time (vacation, etc.) when I'm carrying it on my belt and not at home.
What are your habits? Are they safe -- or deadly? According to friends and family, the father who was shot had carried a gun nearly all of his adult life. Habits are a garden; they must be tended, cultivated and sometimes weeded.
