Famous last words (at least with mine)This is not a de-cocker because it isn't cocked. With it in what you call the 1/2 cock position and the safety on you, can't cock it. With the hammer cocked and to take it to half cock would very dangerous plus it would serve no purpose.
With that said in half cock position and a round in the chamber it will not fire when the trigger is pulled and the hammer drops safety on or safety off.
(at least with mine)
Hope that made some sense.

I would carry cocked and locked in a holster and not use the half cock position.
