You guys do as you will... But as for me, since I am not in a situation that demands I fight off hoards of enemy combatants but I DO carry my weapons day to day in situations that involve those I hold dear to me, I can think of no greater safety 'mechanism' then an empty chamber. Where I not confident in my skill level I wouldnt trust even that, however I too carry and have carried and used my weapons daily for years.... And those years have taught me that taking ANY chance, when it is unnecessary, is fool hardy and is an accident waiting to happen. If I ever have reason to fear Santa Anna's troops breaking into my home in the middle of night, then I may rethink that stance... Until then I will continue to hold and value the safety of my loved ones as dear as I do now.
Conversely, cloth is generally deemed a fairly safe object in most cases as well... In fact I use it VERY safely, each and every day of my life. Yet I still wouldnt put some of it over my eyes and drive around town with the grandkids in the car.
