My SW9GVE's trigger feels remarkably similar to the DA triggers I've observed on my N-frame S&Ws - smooth, and a bit on the heavy side. It's not an issue with the N-frame, as I only fire six rounds before I get a break. As you get to the bottom of the seventeen rounds, though, that pull will start to wear on a fellow.
Doesn't mean there's anything wrong with the gun, just that seventeen is a lot of pulls on a trigger of this sort. Man up, my friend.
That's how the gun was engineered. If you think you know more about how the gun should work than the folks who designed it, by all means futz with it.
Me, I'm leaving mine as it came.
