Thanks, I’m a 1911 shooter and carry cocked and locked. I’m not a big Glock fan (no problems with them)so I don’t keep up with them.
Even a cocked-and-locked single action like your 1911 or my favored Browning High Power has been known to go off when some idiot pulls the trigger - even with the safety on.
The only safety that matters is the one between your ears. Too bad DEA/NYPD?etc., don’t seem to teach that.
The hard and fast rule of gun safety is: “Unless you’ve personally cleared and verified the gun first, all guns should be treated as if they will go bang when you touch the trigger.”
