Do you actually know anything about firearms?
Just the NRA safety handgun safety course where it was greatly discouraged to have a round chambered, but if you being a god of firearms say it is ok, then I will submit.
The reasoning sounded sound enough for me, but by all means, you trust the safety. I will just make the nice sounding (music to my ears) sound of chambering the round when it might be needed. To each his own.
