My Kahr P40 trigger WAS lighter and smoother than my wife's MK9 or the other 2 kahrs I've owned. But after the "walking trigger pin" fix, it's not as light since arriving back from the factory. It's still shorter, and I still like it, but it's definitely heavier now.
Even so, the elite trigger is worth it (to me) as I can feel the difference in the shorter, slightly smoother pull. I'm considering having the elite trigger put in her MK9 as well, to make it a tiny bit closer to the workings of her Glock 19 nightstand gun.
