Am I missing something or are there just no gun owners here. This is incredibly disingenuous, and even dangerous, “advice”.
A loaded gun with a round in the chamber should fire when the trigger is pulled, every single time. They should not fire when the trigger is not pulled.
Following any one of the three safety rules prevents 100% of “accidents”. There are no real gun accidents besides catastrophic mechanical failure (which does happen, but usually with shit ammo and shit guns or poorly maintained guns).
Depending on traditional safeties encourages poor gun handling habits and adds precious time to fire when milliseconds count. “Safety-less” pistols will not fire unless the trigger is pulled, period.
