I was presuming "smooth" to start with. I have a 625-10 that went back to S&W for a master action job. The actual pull weight is about 12 pounds - most people estimate it at 6-8 pounds. "Smooth" definitely trumps "light".
I was also wondering about how H&K measures their trigger pulls to 1/100 pound and what kind of variation they get, if any?
