One of the first lessons any cadets in U.S Military Academy learn in their first year is the 3-second rule. It is, to keep yourself always prepared, it is, of course, best that you should carry your guns with you, but if you don't or you can't, you should leave the guns somewhere visible, reachable and only 3 seconds or less away from you. So if something wrong happen, you can immediately grab it and be ready.

Dragon Gun Mount is the best replacement for gun owners when they're home or driving. Put your gun under your table, under hand wheels or right on your door. Because it would be pretty ridiculous when carrying a big fat gun in front of your wife & kids while eating sandwiches or reading books.

Otherwise, according to the U.S. Department of Justice, "about 1.03 million home invasions occur each year". So, it's best that we gun-owning folks apply the 3-second rule ourselves.
