I'm not bitching at you, but I am trying to point out the differences in when it goes bang or not.
Yes, it's a safe. As long as the trigger is not depressed by whatever means. Trigger pull is typically the last step in firing a weapon.
One more time. It does not have the safety features of either a revolver, or a 1911! With the 1911, the grip safety has to be depressed as well as the trigger. With a revolver, it is going to require twice the pressure to depress that trigger.
And that's about all there is to it.
One more time. AD's are strictly caused by the user of the weapon. For whatever reason.
