Step by step, we are coming to the day when every gun will have to at all times be "disabled" with an "approved" safety device while locked in an "approved" safe, with the govt retaining the right to "inspect" all "private arsenals" (two guns or more, 100 rounds of ammo or more.)
That's the other reason I hate these "safety" gadgets, when what is needed is to firmly teach every 8 year old and older to treat ALL guns as cocked and loaded at ALL TIMES, while keeping them safely away from smaller kids.
