No matter how mindful I can be - I do not trust myself without an external safety. I can manipulate the safety on my Ruger 1911 using only the braille method. It is second nature. Only thing that provides me assurance when a round is chambered and the hammer is up.

I never chamber a round except on the range. I have grandchildren underfoot a lot of the time, thank God for undeserved blessings, so I accept the decrease in readiness for the sake of safety.
