To be fair, my H&K 9mm has basically no safety. 
It is perfectly safe in my hands as I ahve training and experience. Don’t put one in the chamber and it can not fire. (Don’t forget gun safety rule number one, of course.)
Some modern semi autos are more dangerous than older handguns in the hands of people that do not know about firearms.
That begs the question why does a person not knowledgeable about firearms have one.
