I am open minded here, please explain how the hammer can move the firing pin forward when the hammer is up against the back of the slide and the firing pin is not protruding from the face of the slide, the firing pin is a inertia type, when the hammer hits it it moves forward and hits the primer.The 1911 is dangerous to carry in condition 2. It is a condition 1 or 3 firearm. There is a caveat. Colt created the series 80 so that a 1911 could safely be carried in condition 2. The hammer can be hit with enough force to cause a discharge. If you look at the underside of a series 80 slide, you will see a little button where the firing pin (segment) is misaligned and when you pull the trigger, the button is pushed simultaneously and brings the pin segments into alignment.
No matter how hard the hammer is hit if it is against the back of the slide there is no way it can move the firing pin.
