Just fondled my first one yesterday. Understand that my finger knows only 'duty' and service guns and their triggers. Though I've shot well-worked 1911's a time or two, the top TWO triggers on modern service autos have been the Walther PPQ and the Caracal. Again, I am talking out-of-the-box, unmodified.
The LC9s made me GUSH, I tell you. I had absolutely NO disturbance of the sight-picture, and a beautiful let-off. No sproing-nor twang in any way, as with Glock, or Shield. I am smitten, I truly am. The ONLY THING left wanting now, is the lack of stainless steel. But, that trigger is the cat's ARSE, I tell you!
