Firing pin blocks are a recent safety addition, no? I prefer uncocked DA carry, and never unholster but for shooting, cleaning, or storage. Ok, defense too should the need arise. All my firearms are always loaded whether bullets are present or not. The gist here is I am the greatest safety feature of a firearm and take that responsibility seriously as we all should. It's nice to be aware and considerate of the other safety features a firearm has, but I am the most important one.
Thanks for the info.
