I have had the same great results! Although mine is post recall production date. I bought some super cheap ammunition just to try and make it malfunction haha. I really want to put it to the test.
the SA trigger pull force vs distance is more like step function, very little resistance at the "lead" part, then it stopped at the break point, the final break is very crisp and well defined. past made SA resistance increases as you pull the trigger so the final break is not as well defined.Double action (DA) is quite long. SA is very short in comparison.
What do you mean about SA break? I can explain how mine operates if you tell me more what you're looking for.
I still haven't received my Fedex slip (filled out form on website few weeks ago). Any idea how long that takes?
