the hammer never moved. the firing pin floats and hit the primer hard enough to go bang, without the hammer ever touching the firing pin.
look inside and study the trigger mechanism. the safety does ONE THING. it prevents the trigger itself from moving more than a few degrees. it does not touch the hammer, firing pin, or other parts
also, i totally agree with the 4 rules approach, but that only applies to when you are handling the gun. when it's stored, or on a shelf or something, you have to understand the details of the gun itself to understand what is "safe" and "not safe".
that is one reason california, despite a lot of whining from us, makes pistol mfg certify their guns are drop safe. lots of bolt gun triggers are bad enough (lack safe amount of sear engagement) that jarring them will set the gun off. don't even get me started on open bolt full auto sub guns
know your gun
btw, one more condition to consider is the use of a chamber flag. basically, chamber flag inserted, bolt closed on the flag, hot magazine inserted. that requires you to cycle the bolt and remove the flag. it takes an extra step but gives you a higher degree of confidence that there is not a round in the chamber when the gun is just standing against the wall unattended
