I totally agree with the title if "safety" means user safety. Every single pistol AD I've ever seen on a range has been due to operator error (finger on the trigger when it shouldn't be). I also agree with OT about using a proper holster to prevent AD's. I haven't personally heard of any "string in a holster" incidents as mentioned by hookeye but am deferring to him on that as he is apparently aware of some and I can understand the principle.
