I Love my Glocks. The safe action system is good but no its not like a regular safety. Learning the proper techniques to deal with a pistol is needed for any pistol without them the number a safeties does not mater, accidents will happen.
I like guns without a external safety. They are easy to learn how to properly use by someone that will not use the pistol as much as I do. My fiance for example is not into guns, or snakes, but I have taught her how to shoot and use the guns in or home. She knows that when she grabs a Glock it is ready to go. Since people under stress forget things and hitting the safety off turns into a big deal when your trying to shoot an attacker, not having to deal with one is nice.
A Glock is also easy to break down and clean. Many people buy guns have guns and hardly clean them or don't clean them correctly because of the way they break down. You can not get much simpler than a Glock.
