I have half a dozen handguns for HD, and the whole point is NONE of them are secured in anything that would restrict or delay their immediate acquisition and deployment if necessary. They are of course, concealed in discreet places in the various rooms of my home, but the whole idea of HD is to "have a gun" RIGHT NOW - not in a minute or two after traveling to a distant room and fingering a safe. During a home invasion, a lot can happen in the first 10 seconds; purposely "securing" a HD gun so it cannot be quickly retrieved from wherever you happen to be about the premises is to completely miss the point.
Yeah, yeah, I know all about the child safety argument - your own kids and their untrained friends and all, and that might make some small difference in storage decision-making. My suggestion for situations where your kids' friends might be sleeping over and such is to lock away your guns, but home carry one on your person! Rule No.1 is always "Have a gun."
