I have a CZ70. It is a traditional double action semi-auto pistol (first round double action, subsequent rounds single action). With an empty gun, I can rack the slide to the rear, setting the hammer in its single action position. If I ride the slide forward into battery the hammer will remain set in its single action position and I can pull the trigger and the hammer will fall. If I rack the slide and release it to go into battery under its own power, the hammer follows as the slide slams to a stop in battery. With the gun loaded and shooting the first round in double action, the round fires and the gun cycles firing the second round as the hammer follows the slide. It will then produce a stoppage with a failure to eject. I feel as though I may have a runaway gun if it could cycle the entire mag without the failure to eject. What I do know about guns leads me to believe there is something going on between the sear and the hammer. Can anyone confirm or deny my assumption?
