No even close. There have been so many Negligent Discharges from Glocks due to lack of training that when gun people hear of an ND the assumption is that it involves a Glock. You'll notice that I stated a lack of training. There is nothing wrong with the safety designs of the Glocks. It's the owners who can't keep their fingers off the triggers.
My favorite story of a Glock is the officer who enter the washroom stall and then hung the Glock from the door hook like he had when he used a revolver. The mag was emptied and all 15 shoots discharged. Some of the rounds went through the ceiling and through the upper floor. It's funny because no one was hurt.
