I was thinking more along the lines of what happens during actual shooting, when one goes by feel and one looks at the target rather than at the hammer.
Since nothing on Glocks, Kahrs or Kel Tecs starts moving when a trigger is pulled, novices who use these pistols have to practice and become non-novices by concentrating on tactile rather than visual clues as to the moment of discharge. A Para Ordnance with no pseudo hammer and only a long S-A trigger pull would be akin to one of these pistols on learning when firing is about to take place.
I like visible hammers because visible hammers clearly show the safety condition of the pistol. If the hammer on one of our pistols somehow got stuck to the rear after chambering a round, I don't think anyone would holster and carry that pistol. They’d immediately be aware of the danger.
With a striker fired pistol, one can never be absolutely sure of the position or condition of the striker. I don't mean by that statement to suggest striker fired guns are dangerous. I just like reaffirmation of safety in the form of a fully exposed hammer. When the hammer on one of our pistols is seen as being fully forward, it is in fact fully forward. The hammer one sees is the hammer one gets.
The importance of keeping guns pointed down range after a misfire generally apply to striker fired weapons. What usually happens is not a misfire but a striker that has been held back by dirt or some other mechanical means. When the means holding the striker back are removed or jarred loose, the striker may charge forward to fire the gun. These delayed discharges are likely not hang fires caused by primers sitting on the edge, but far more likely the result of a striker suddenly released after hanging back on a thin thread.
I believe the Para Ordnance is a safe pistol; however, after a round is chambered the owner of a Para Ordnance should know the pistol is carried with the real hammer fully cocked and that the visible hammer is not a hammer by any accepted gun terminology definition.
