I understand my 3rd generation pt111 pro is supposed to be sa/da. And when there's a round in the chamber the trigger has a lot of dead space before firing. As I understand it, that dead space is the single action part of the equation. But when there's nothing in the chamber (ie. dry-firing, which I understand is fine for centerfire pistols) the trigger pull is much heavier all the way through. This is the double-action part, yes? Now, when the whole thing is empty and I bring the action back a quarter inch the trigger goes back to single action. My question is this - much as I respect the safety I would just as soon leave the gun loaded and in double-action mode, no safety but heavier first pull. But I can't figure out how to "uncock" the gun without emptying the chamber. Can someone tell me what I'm seeing and let me know if what I'm asking is possible?
