Since I was nine years-old I’ve been trained to keep my finger off the trigger until I want to put a hole in something. The ignition system of a Glock is not all that different, in my mind at least, from a revolver. I have not had a problem anything like the one this cop has had
There are many things that can pull the trigger, besides your finger. In this case it could be the shirt or the pants. And even the finger - when the weapon fell down he had to fish for it under the belt, blindly. Carrying a firearm this way is pretty stupid anyway. But familiarity breeds contempt.
I personally don't touch Glocks. I understand that the safety is not the ultimate prevention of accidents. However nothing in the world is such an ultimate solution. If you eat an apple every day you still can die young. If you visit a doctor periodically for a check-up you still can die young. If you run a mile every day you still can die young. But when you combine all three, and more, then you'd be in a pretty good shape, if you ask me.
Also any security professional will say that the security must be always layered. A good neighborhood, a police station across the road, a fence, a dog, a solid door, a good lock, and a Mossberg behind that door all work together. That's why I insist on firearms with mechanical safeties. I do not trust them, but I use them because it is just possible that one day a mechanical safety proves to be very useful.
With regard to the instant bang with a Glock ... I am not the agent 007. My bias is to not shoot, rather than to shoot. But if one day we find ourselves in the Mad Max universe, the solution is simple. Flip the safety lever to "Fire" and leave it there. You can even weld it there if you want to :-) Glock just takes a useful function away from you, but does not add any.
I suppose. To me the trigger pull of a GLOCk compared to say a typical .38 is markedly lighter.
