That is very good safety practice. Double action semi-autos are a little safer because you can carry hammer down with a firing pin block, like my PPK/S. One of the reasons that the Law enforcement agencies that don't use striker fire firearms, like the Glock, issue d/a semis. You really have to pull the trigger to fire one on the first shot. If my safe was next to my bed, I couldn't get to my bed. Main safes are in the walk-in closet. My home security consists of a hard wired alarm system with motion detectors. 4 dogs. Three small, loud, terriers that bark at everything that sleep in the house at night. Bedroom doors closed. It doesn't do any good to be asleep if someone gets in. You shoot the one in your hand not the one in the safe. It is fine to have loaded magazines handy but again the one that is in your hand is the one that you are using. May-by until you get to our safe, if you are at home. You should have a plan when the SHTF. Not wait til it happens. Be aware of what's going on. Sorry but I have been handling firearms for over 50 years and I don't have one of those " whoops stories. " I have sent my wife, daughters and all of my grandchildren, that are interested-don't force them, to certified NRA gun safety courses and instructors. . It is better to have someone that is neutral, not a family member, do their initial safety training. After that it is like anything else that you like to do. Bowling, drone flying, auto racing etc...practice, practice, practice. The more familiar that you are with your firearms, the safer and more effective you will become. Please don't be the guy that said " it was an accident, I didn't mean it." No such thing as an accident. All are preventable.
