Not sure, but it made me want to try my LEM to see. Mine makes a clicking sound at about 1/8 pull only if you try to dry fire it after it's been cleared and fired. If you rack the slide, the trigger doesn't make a sound at all.
The trigger pull should be much harder in the first state I described, but it's not a normal state for the gun. Once you've put a magazine in and chambered a round it won't do that.
The hammer really never "cocks", it's pulled back by the trigger (or the action from firing) and held in place by the trigger for followup shots.
