From my first NRA handgun course, the instructor (a retired police officer) said to have a gun on you. Do you have one in the bathroom, the basement, the laundry room, the garage - stand at the farthest part of a room, how long does it take to get to the gun and get it out of it's container - assuming you don't just leave loaded guns lying in the open? It's a long time in action time.
Yes, we also have a long arm or other handguns available IF we have time to get to them. But, boringly repetitive - the stashing of guns around the house without one on you is, is not optimal. It indicts a naivety in a list of such that surface here periodically. Recently we seen:
1. Signs with guns around the house.
2. Don't need or want an alarm because police response is too slow. Trust totally in Fido.
3. Shoot in the leg to inflict pain
4. Ignore advice about legal risks of various silly behavioral patterns that have legal consequences. It's a good shoot and show me a case!
5. Open carry
6. Having your extra magazine on the same side as your handgun in OC.
7. Stashing guns without carrying one.
There are others, that's for another day.
