As stated earlier, people have shot themselves in the leg long before glock was around with every type of gun made.
A "safer gun" isn't the answer. A "safer person" is the correct answer which of course applies to the operation of every firearm and every "tool" for that matter.
Now to get myself back on topic, there is a video linked on this forum somewhere of a store owner who got the jump on a couple of guys robbing his store. He pulled the trigger on his 1911 and nothing happened. As paramedics were working to save his life after he was shot by the bad guys, he kept saying "I forgot the thumb safety".
If you are going to carry a firearm with a thumb safety you better practice drawing and firing that weapon until you have developed the muscle memory that allows that action to take place without thought and without hesitation. If that is true with a thumb safety imagine how much more practice would be required to develop the muscle memory required for the much more complex action of chambering a round.
This is all of course simply my opinion which is worth what it cost.
