<i>This makes no difference at all in the deterrence scenario</i><p>Yeah, right, we&#x27;re going to trust these &quot;phone home&quot; devices that much?<p>In fact, how do you know they&#x27;re working, for police or civilians, unless they phone home every month or so, or at least when taken out of their metal safes.<p>In the current climate of bad faith, where our adversaries latest campaign for &quot;gun safety&quot; does nothing of the sort (and claims we don&#x27;t care about it during a period where both the population and guns owned increased by roughly 50% and the absolute number of accidental gun deaths dropped by 25%; it is we gun owners who achieved that, not the gun grabbers)?<p>There&#x27;s also the mass and volume problems.  Not everyone can get away with carrying a near full sized M1911 like I can (originally a military service pistol, my carry model sacrifices some life with an alloy frame and some power with a 4 inch barrel).  Require these and you will preclude a whole lot of concealed carry, and I for one would not like the extra mass, let alone having to replace some perfectly fine firearms.
