I think the "decocker " was made spring loaded for the CHP. So many people ,civilians and officers were decocking the pistols and forgetting to push it up into the firing mode. I heard that one officer almost died because he was involved in a shoot out and could not figure out why his pistol would not fire. True ,I don't know . I asked a local Police firearms instructor about this pistol and that's the story he had to tell. But it does make perfectly good sense. Plus I have seen many cases of the decocker being bump accidentally into the non firing position and officers did not know it. I think that's the reason that the FBI's 1076 had frame mounted decockers.
