If I ever need to use my Glock to defend myself, I want it to go 'bang' when I pull the trigger. The rest of the time it stays in my holster that fully covers the trigger guard, and never becomes the object of "show and tell."
The Glock is no more dangerous than my double action revolvers. And if the factory 6.5 lb trigger pull is too light for your comfort, you can change trigger springs all the way up to the NY2 spring which gives a revolver like 12+ lb trigger pull.
Yes. The trigger bar that disengages the firing pin safety.
