Check the you tube video "DEA officer shots himself in classroom". In front of a classroom full of children, a DEA officer talks about his Glock 40 and how he is the only one in the room professional enough to use one-this 20 seconds before he accidentally puts a hollow point into his leg. We'd have to guess as a DEA agent he is well trained with his Glock 40, but he has an accidental discharge having a lapse in his thought process. Can happen to anyone. The only pistol I've ever felt entirely comfortable carrying without a safety is the LCP because the trigger travel is 49 inches and it takes two fingers to pull the trigger. Slight exaggeration, but you know. As a S&W 39 series guy for years, the SR-series gets high marks for safety and performance.
